Matches

Show answer & explanation

Answer

Scale of Preference matches with a list of unsatisfied wants arranged in order of relative importance. Priority Ranking matches with placing the most pressing needs at the top and less pressing ones at the bottom. Choice matches with the act of selecting the most urgent want from a list of desires. Opportunity Cost matches with the real sacrifice or alternative forgone when a preferred want is satisfied.
A scale of preference is a list of unsatisfied wants ordered by importance. Ordering wants by urgency represents priority ranking. Selecting an item from the scale is making a choice, and the alternative given up in the process constitutes the opportunity cost.

Step-by-Step Solution

1
Identify the primary definition of a Scale of Preference.
Recognize that a scale of preference is a structured list of unsatisfied wants sorted by importance.
This establishes the fundamental framework of consumer choice under scarcity.
2
Differentiate between priority ranking, choice, and opportunity cost.
Priority ranking is the ordering mechanism; choice is the selection action; opportunity cost is the resulting sacrificed alternative.
Distinguishing these core concepts prevents confusing monetary expense with economic opportunity cost.

Question 2Question

A student with a limited budget of N12,000\text{N}12,000 constructs a scale of preference listing four items in descending order of priority: Textbooks (N7,000\text{N}7,000), School Shoes (N5,000\text{N}5,000), Scientific Calculator (N4,000\text{N}4,000), and School Bag (N5,000\text{N}5,000). Match each aspect of the student's economic decision on the left with its corresponding concept or interpretation on the right.

Items

Selecting Textbooks and School Shoes for purchase
Forgoing the Scientific Calculator
Ranking Textbooks higher than School Shoes
Inability to purchase all items on the list

Matches

Show answer & explanation

Answer

The correct pairings are: 'Selecting Textbooks and School Shoes for purchase' matches 'Satisfaction of effective demand within the income constraint'; 'Forgoing the Scientific Calculator' matches 'Opportunity cost (real cost) of the selected items'; 'Ranking Textbooks higher than School Shoes' matches 'Evaluation of relative marginal utility'; and 'Inability to purchase all items on the list' matches 'Direct consequence of scarcity of economic resources'.
A scale of preference is a list of unsatisfied wants arranged in order of relative importance. It enables a rational consumer to maximize utility under income constraints. Here, purchasing Textbooks and Shoes fulfills effective demand within the N12,000\text{N}12,000 limit. The highest-ranked unfulfilled want, the Scientific Calculator, is the opportunity cost. The ordering of items reflects relative marginal utility, and the overall shortfall of funds illustrates scarcity.

Step-by-Step Solution

1
Calculate total expenditure from available income
Income = N12,000\text{N}12,000. Purchasing Textbooks (N7,000\text{N}7,000) and School Shoes (N5,000\text{N}5,000) exhausts the budget total (N12,000\text{N}12,000).
Determines which wants become effective demand.
2
Identify the opportunity cost of the choice
The next highest priority item that remains unfulfilled is the Scientific Calculator (N4,000\text{N}4,000).
Opportunity cost is defined as the next best alternative forgone, not the total monetary outlay or all unfulfilled wants combined.
3
Analyze the priority order on the scale of preference
Textbooks are ranked above School Shoes because they yield higher relative marginal utility to the student.
A scale of preference ranks wants according to their urgency and utility to the individual.
4
Relate unfulfilled wants to underlying economic principles
The total cost of all desired items is N21,000\text{N}21,000, exceeding the N12,000\text{N}12,000 income.
Demonstrates economic scarcity, forcing the individual to make choices based on a preference schedule.

Question 3Question

A consumer with a limited budget constructs a scale of preference to allocate income among several competing items. Based on the economic principles of urgency and necessity, in what order should the consumer rank these items from highest priority (most urgent) to lowest priority (least urgent)?

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct order from highest priority to lowest priority is: Purchasing daily basic food supplies, Buying essential prescribed textbooks, Purchasing a new pair of designer shoes, and Acquiring a high-end video gaming console.
A scale of preference is a list of unsatisfied wants arranged in order of relative importance or urgency. Basic survival needs rank highest, followed by urgent functional needs, comfort upgrades, and lastly non-essential luxury items.

Step-by-Step Solution

1
Identify primary basic survival needs.
Basic food supplies satisfy fundamental physiological survival, placing them at the first position.
Survival needs must be satisfied before secondary wants or needs can be considered.
2
Identify essential functional and educational needs.
Prescribed textbooks required for upcoming examinations occupy the second position.
Textbooks are an urgent necessity for academic performance with immediate time sensitivity.
3
Distinguish between comfort upgrades and non-essential luxuries.
Upgrading functional shoes occupies the third position, while the high-end gaming console occupies the fourth position.
Comfort upgrades take precedence over pure luxury entertainment items, which sit at the bottom of the preference scale.

Question 4Question

A farmer with an available capital of N250,000\text{N}250,000 lists his pressing farm needs in order of priority as follows:

1. Purchase of high-yield seeds (N250,000\text{N}250,000)
2. Construction of an irrigation channel (N200,000\text{N}200,000)
3. Hiring additional farm labor (N150,000\text{N}150,000)
4. Installation of solar pest repellers (N100,000\text{N}100,000)

If the farmer allocates his entire budget to satisfy the highest priority item on his scale of preference, what is the opportunity cost of his decision?

Show answer & explanation

Answer: The construction of an irrigation channel

Answer

The construction of an irrigation channel
A scale of preference arranges wants in descending order of importance. When a consumer or producer makes a decision based on a scale of preference, the opportunity cost is the immediate next best alternative that is sacrificed. In this scenario, purchasing high-yield seeds is the first choice, making the construction of an irrigation channel the most preferred alternative foregone.

Step-by-Step Solution

1
Identify the item selected based on the scale of preference
The farmer selects the purchase of high-yield seeds (N250,000\text{N}250,000), which uses up the entire available budget.
Economic agents satisfy wants starting from the highest priority on their scale of preference.
2
Determine the next best alternative on the scale of preference
The item directly below the chosen item in order of priority is the construction of an irrigation channel.
Opportunity cost is defined strictly as the real cost or next best alternative sacrificed when a choice is made.

Matches

Show answer & explanation

Answer

The correct pairings match: arranging wants by urgency with establishing a framework for rational decision-making; selecting the top item with maximizing utility from limited income; forgoing the second item with incurring real opportunity cost; and re-ordering items during price changes with adjusting priority to reflect budget constraints.
Constructing a scale of preference enables consumers to make rational economic choices. The item placed at the top yields highest satisfaction, while the second-ranked item left unpurchased constitutes the real opportunity cost of the selection. Shifts in market prices require adjusting priority ordering to remain within budget limits.

Step-by-Step Solution

1
Analyze the purpose of listing wants in descending order of importance.
Pairs with establishing a framework for rational decision-making under scarcity.
Scale of preference organizes subjective human wants so that limited means are applied systematically to pressing needs.
2
Determine the outcome of fulfilling the top item on the preference schedule.
Pairs with maximizing total utility from limited monetary income.
A rational consumer allocates income to the most urgent item first to attain maximum total satisfaction.
3
Identify the economic concept associated with the second item on the scale that remains unfulfilled.
Pairs with incurring the real opportunity cost of the choice made.
Opportunity cost is defined as the next best alternative sacrificed, which is the second item on a scale of preference.
4
Examine how relative price variations impact consumer preference rankings.
Pairs with adjusting consumer priority to reflect modified budget constraints.
When price changes affect affordability, rational consumers re-evaluate their list of wants to optimize expenditure within budget limitations.

Question 7Question

A commercial printing firm with a capital budget of N500,000\text{N}500,000 intends to acquire equipment to expand production. The proprietor constructs a scale of preference listing potential acquisitions in descending order of priority as follows:

1. Industrial Paper Cutter (N300,000\text{N}300,000)
2. High-Speed Digital Printer (N200,000\text{N}200,000)
3. Heavy-Duty Binding Machine (N200,000\text{N}200,000)
4. Lamination Machine (N100,000\text{N}100,000)

If the proprietor acts rationally by allocating the budget strictly according to this scale of preference, what is the opportunity cost of the decision?

Show answer & explanation

Answer: The Heavy-Duty Binding Machine

Answer

The Heavy-Duty Binding Machine
A scale of preference lists wants in order of priority. Given a budget constraint of N500,000\text{N}500,000, a rational producer purchases the top priority items: the Industrial Paper Cutter (N300,000\text{N}300,000) and the High-Speed Digital Printer (N200,000\text{N}200,000). The next best alternative foregone—which is the item immediately following the last purchased item on the scale of preference—is the Heavy-Duty Binding Machine. Therefore, the Heavy-Duty Binding Machine constitutes the opportunity cost of the choice.

Step-by-Step Solution

1
Determine the items purchased using the scale of preference under the budget constraint
With a budget of N500,000\text{N}500,000, the firm selects item 1 (Industrial Paper Cutter at N300,000\text{N}300,000) leaving N200,000\text{N}200,000, and then item 2 (High-Speed Digital Printer at N200,000\text{N}200,000), leaving N0\text{N}0.
Rational economic agents allocate limited funds starting from the highest priority item on their scale of preference.
2
Identify the unselected items remaining on the scale of preference
The unselected items are item 3 (Heavy-Duty Binding Machine) and item 4 (Lamination Machine).
Budget depletion prevents the purchase of remaining items on the list.
3
Apply the definition of opportunity cost to determine the correct alternative foregone
The opportunity cost is the next best alternative foregone, which is the Heavy-Duty Binding Machine.
Opportunity cost is measured by the real sacrifice of the single highest-ranked alternative that cannot be satisfied due to scarcity.

Question 8Question

An artisan tailor with a total capital budget of N60,000\text{N}60,000 prioritizes her business needs in a scale of preference as follows:

1. Industrial sewing machine (N35,000\text{N}35,000)
2. Electric fabric cutter (N25,000\text{N}25,000)
3. Overlock edging machine (N20,000\text{N}20,000)
4. Backup power generator (N40,000\text{N}40,000)

Assuming she rationally allocates her available capital strictly according to her scale of preference, what is the opportunity cost of her choice?

Show answer & explanation

Answer: The overlock edging machine

Answer

The overlock edging machine
Allocating the N60,000\text{N}60,000 budget according to priority allows the tailor to purchase the industrial sewing machine (N35,000\text{N}35,000) and the electric fabric cutter (N25,000\text{N}25,000). The highest-ranked item she must sacrifice due to limited funds is the overlock edging machine. Thus, the overlock edging machine is the opportunity cost of her choice.

Step-by-Step Solution

1
Calculate capital allocation according to priority
Items 1 and 2 total N35,000+N25,000=N60,000\text{N}35,000 + \text{N}25,000 = \text{N}60,000, completely utilizing the available budget.
A rational decision-maker satisfies wants in strict descending order of priority until income is exhausted.
2
Identify the next best unsatisfied want
The highest-ranked item that could not be acquired is Item 3, the overlock edging machine.
Opportunity cost is defined as the next best alternative foregone when a choice is made.

Question 9Question

A tailor receives a monthly allowance of N40,000\text{N}40,000 and arranges her pressing business needs in order of priority as follows:

1. Sewing machine maintenance: N20,000\text{N}20,000
2. Purchase of dress fabrics: N20,000\text{N}20,000
3. Workshop electricity bill payment: N15,000\text{N}15,000
4. Purchase of a new smartphone: N15,000\text{N}15,000

If she allocates her entire allowance strictly according to her scale of preference, what is the opportunity cost of her choice?

Show answer & explanation

Answer: The workshop electricity bill payment and the smartphone foregone

Answer

The workshop electricity bill payment and the smartphone foregone
By following her scale of preference, the tailor allocates her N40,000 to the top two priority items: sewing machine maintenance (N20,000) and dress fabrics (N20,000). The opportunity cost of this choice is the real sacrifice made—specifically, the workshop electricity bill payment and the smartphone foregone.

Step-by-Step Solution

1
Calculate total expenditure by summing costs of items in order of priority until income is exhausted.
Items 1 and 2 cost N20,000+N20,000=N40,000\text{N}20,000 + \text{N}20,000 = \text{N}40,000, which fully exhausts the available N40,000\text{N}40,000 allowance.
A scale of preference requires satisfying wants starting from the highest priority item downwards until income is exhausted.
2
Identify the unfulfilled wants that could not be purchased due to scarcity of funds.
Item 3 (Workshop electricity bill payment) and Item 4 (Purchase of a new smartphone) are left unsatisfied.
Scarcity limits consumption choices, leaving lower-ranked items on the scale of preference unfulfilled.
3
Determine the opportunity cost of the decision.
The real cost is the workshop electricity bill payment and smartphone foregone.
Opportunity cost is defined as the alternative wants sacrificed when a choice is made.

Question 10Question

A rational student operating under a tight budget constraint needs to construct a scale of preference to allocate a limited monthly allowance of N25,000\text{N}25,000. Arrange the following competing items in descending order of priority (from top priority to lowest priority) according to the economic principles governing a scale of preference.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct order from top priority to lowest priority is: 1. Daily basic nutritional food expenses required for physical sustenance during the academic session, 2. Mandatory course textbooks required for passing upcoming continuous assessment examinations, 3. Subscription for a monthly high-speed internet data plan used for general research and communication, 4. Purchase of high-end designer apparel for an optional end-of-term campus party.
A scale of preference is a list of unsatisfied wants arranged in order of relative importance and urgency. A rational consumer prioritizes essential survival needs (food) first, followed by critical functional needs (mandatory textbooks), secondary comforts (internet subscription), and lastly luxury or non-essential items (designer party apparel).

Step-by-Step Solution

1
Identify primary basic survival needs
Daily nutritional food expenses represent indispensable physiological needs.
Economic rationality dictates that physiological survival needs must be satisfied before any higher-level or secondary wants.
2
Identify primary functional and urgent obligations
Mandatory course textbooks required for upcoming exams rank second.
Textbooks represent urgent functional wants directly aligned with the student's core objective of academic performance.
3
Identify secondary comforts and utility-enhancing items
Monthly high-speed internet data plan ranks third.
General communication and research data plans provide secondary utility and comfort, ranking below mandatory academic materials.
4
Identify non-essential luxuries
Designer apparel for an optional social party ranks last.
Luxury goods and social leisure wants carry low marginal utility relative to cost under strict budget constraints.

Show answer & explanation

Answer

Listing community infrastructure projects in order of importance matches the formulation of a scale of preference based on rational prioritization. Selecting the healthcare center while setting aside the park matches making an economic choice under scarce resources. The foregone park project matches the realization of opportunity cost. Attaining maximum community satisfaction matches efficient allocation of resources to maximize total utility.
Each decision-making stage directly maps to a foundational principle of basic economic concepts: constructing a scale of preference involves ranking items by urgency; selecting a specific item demonstrates choice dictated by scarcity; the unchosen item represents opportunity cost; and systematic prioritization leads to efficient resource allocation.

Step-by-Step Solution

1
Analyze the action of listing projects systematically before expenditure.
Identified as creating a scale of preference, which ranks wants according to priority.
A scale of preference is defined as a list of unsatisfied wants arranged in order of relative importance.
2
Evaluate the act of choosing one specific project over another due to budget constraints.
Identified as economic choice under scarcity.
Scarcity of funds forces economic agents to make choices among competing alternatives.
3
Identify the economic nature of the project that was sacrificed.
Identified as opportunity cost.
Opportunity cost is the alternative foregone when a choice is made.
4
Evaluate the overall economic outcome of satisfying urgent wants first.
Identified as efficient resource allocation maximizing total utility.
By prioritizing higher-ranked items, a consumer or firm ensures optimal satisfaction from limited financial resources.

Question 12Question

An agro-processing cooperative with a capital budget of N250,000\text{N}250,000 arranges its immediate expenditure needs in order of priority on a scale of preference as follows:

1. Repair of main grating machine — N150,000\text{N}150,000
2. Purchase of hydraulic press — N100,000\text{N}100,000
3. Installation of a solar drying shed — N100,000\text{N}100,000
4. Procurement of cassava tubers — N80,000\text{N}80,000

If the cooperative spends its budget strictly according to this scale of preference, what is the opportunity cost of acquiring the hydraulic press?

Show answer & explanation

Answer: The installation of the solar drying shed

Answer

The installation of the solar drying shed
A scale of preference lists wants in order of importance. Given a budget constraint of N250,000\text{N}250,000, the cooperative allocates N150,000\text{N}150,000 to item 1 and the remaining N100,000\text{N}100,000 to item 2 (hydraulic press). The opportunity cost of selecting the hydraulic press is the most desirable alternative sacrificed due to that decision, which is item 3, the installation of the solar drying shed.

Step-by-Step Solution

1
Determine which items are satisfied given the budget constraint
With a total budget of N250,000\text{N}250,000, the cooperative satisfies item 1 (Repair of main grating machine at N150,000\text{N}150,000, leaving N100,000\text{N}100,000) and item 2 (Purchase of hydraulic press at N100,000\text{N}100,000, leaving N0\text{N}0).
A rational decision maker satisfies wants in order of priority from top to bottom on the scale of preference until the budget is exhausted.
2
Identify the foregone alternatives resulting from choosing the hydraulic press
The expenditure of the remaining N100,000\text{N}100,000 on the hydraulic press prevents the cooperative from choosing items 3 and 4.
Choosing to purchase the press consumes funds that could otherwise have been used for lower-priority needs.
3
Select the highest-ranked alternative foregone to find the opportunity cost
The highest-ranked unsatisfied item is item 3: the installation of a solar drying shed.
By definition, opportunity cost is the next best alternative foregone, not the financial cost or all unsatisfied wants combined.

Question 13Question

A civil servant receiving a fixed monthly salary constructs a scale of preference to allocate limited financial resources. Based on economic principles of urgency and relative importance of wants, arrange the following spending needs in order of priority from highest priority (most urgent) to lowest priority (least urgent).

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct order of priority from highest to lowest is: Purchase of essential food items for monthly household consumption, Payment of residential house rent due for the month, Payment of children's school tuition fees for the upcoming academic term, and Acquisition of a designer wristwatch for social events.
A scale of preference is a list of unsatisfied wants arranged in order of relative importance and urgency. A rational economic agent prioritizes basic physiological survival needs (food) first, followed by essential shelter (rent), critical family investments (education), and finally non-essential luxury goods (designer wristwatch).

Step-by-Step Solution

1
Identify basic survival necessities
Essential food items are prioritized first because physical survival is the most urgent unsatisfied want.
Economic rationality dictates that basic physiological needs take precedence over all other expenditures on a scale of preference.
2
Identify shelter and housing obligations
Payment of residential house rent is placed second.
Basic shelter secures protection and stability, making it secondary only to immediate sustenance.
3
Identify important social and educational investments
School tuition fees are ranked third.
Tuition fees represent critical long-term developmental priorities, ranking ahead of optional luxury consumption.
4
Identify luxury and non-essential wants
The designer wristwatch is placed last.
Luxury goods yield non-essential satisfaction and are deferred when financial resources are limited.

Question 14Question

A commercial poultry farmer operating under a strict budget constraint needs to construct a scale of preference to guide farm expenditure. Arrange the following financial needs in order of priority, from the most urgent (highest priority) to the least urgent (lowest priority).

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct priority sequence from most urgent to least urgent is: Purchasing essential livestock vaccines and feed, followed by Repairing damaged feeding troughs and water supply pipes, then Installing automated lighting timers, and finally Repainting the administrative office block and exterior boundary fence.
A rational economic producer constructs a scale of preference by arranging needs according to urgency and utility. Livestock feed and vaccines ensure immediate survival and prevent catastrophe, making them the most pressing need. Maintaining basic operational equipment like feeding troughs comes next to sustain production. Productivity-enhancing technologies like lighting timers follow as secondary growth objectives, while cosmetic items like office painting carry the lowest urgency.

Step-by-Step Solution

1
Identify the primary function of a scale of preference.
A scale of preference ranks unsatisfied wants in order of importance and urgency to enable rational decision-making under scarcity.
Economic agents must satisfy basic survival and core operational needs before allocating scarce resources to capital enhancements or aesthetic luxuries.
2
Evaluate and rank each expenditure item based on urgency and necessity.
Essential feed and vaccines safeguard livestock survival (top priority). Repairing basic feeding equipment secures daily operations (second priority). Installing production-boosting lighting enhances yield (third priority). Office painting is purely cosmetic (lowest priority).
Ranking wants logically reflects the degree of urgency and opportunity cost involved in farm management.
