A firm processing fresh oil palm bunches into crude palm oil establishes its mill directly adjacent to plantations in Imo State, whereas a industrial bakery producing bread establishes its plant near high-density urban residential centers in Lagos. Based on industrial location principles, what primary economic rationale accounts for the contrasting site choices of these two production activities?

A bakery in Benin City allocates its daily supply of flour to produce either 100 loaves of bread or 50 meat pies. Currently, the bakery produces 20 meat pies. If the baker decides to increase meat pie production to 35 meat pies, what is the opportunity cost of this decision in terms of loaves of bread foregone?

An economy's current equilibrium national income is $\$1,200\text{ billion}$, while its full-employment potential national income is $\$1,500\text{ billion}$. The consumption function is $C = 150 + 0.75Y_d$, where $Y_d$ is disposable income ($Y_d = Y - T$), and the tax function is $T = 40 + 0.20Y$, where $Y$ is national income. To achieve economic stabilization at full employment using fiscal policy, by how much (in billions of dollars) must the government increase its expenditure ($G$)?

A nation's total federal budget of $₦500\text{ billion}$ is allocated across four key sectors: Health ($₦125\text{ billion}$), Education ($₦175\text{ billion}$), Defense ($₦120\text{ billion}$), and Agriculture (the remainder). In a pie chart constructed to represent this budget distribution, what is the central angle (in degrees) representing the allocation for Agriculture?

A member country facing temporary short-term foreign exchange shortages and balance of payments deficits requires financial assistance to stabilize its international currency reserves. Which international economic organization is primarily responsible for providing this short-term balance of payments support?

A consumer's maximum willingness to pay for four successive bags of rice is ₦15,000, ₦13,000, ₦11,000, and ₦9,000 respectively. If the prevailing market price per bag is ₦9,000, what is the total consumer surplus derived in Naira?

A monopolist faces a market demand curve defined by the price function $P = 100 - 4Q$, where $P$ is the unit price in Naira ($\text{₦}$) and $Q$ is the quantity of output sold. If the firm increases its production and sales from $11$ units to $12$ units, what is the marginal revenue generated by the $12^{\text{th}}$ unit?

A firm operating under monopolistic competition faces an inverse demand function $P = 120 - 4Q$ and a marginal revenue function $MR = 120 - 8Q$, where $P$ is price in Naira and $Q$ is quantity of output. Its total cost function is $TC = 200 + 20Q + Q^2$ and its marginal cost function is $MC = 20 + 2Q$. What is the firm's maximum short-run economic profit in Naira?

Match each balance of payments adjustment policy measure on the left with its corresponding policy classification and operational mechanism on the right.

A Nigerian importer requires British Pounds ($\text{GBP}$) to settle an international trade transaction. In the foreign exchange market, the exchange rate between the US Dollar ($\text{USD}$) and the Nigerian Naira ($\text{NGN}$) is $\$1.00 = \text{NGN } 750$, while the exchange rate between the British Pound ($\text{GBP}$) and the US Dollar ($\text{USD}$) is $£1.00 = \$1.40$. What is the cross exchange rate of one British Pound ($£1.00$) in terms of Nigerian Naira ($\text{NGN}$)?

A weight-losing raw material processing firm, such as a palm oil extraction mill in Ondo State, minimizes its total transportation costs by locating near the consumer market rather than near the raw material source.

A developing nation facing a severe short-term foreign exchange crisis requires immediate balance of payments assistance, while a neighboring country requires long-term concessionary financing to construct a hydroelectric dam. Which international financial institutions are established specifically to fulfill these respective functions?

In a foreign exchange market operating under a flexible exchange rate system, the quantity demanded of US Dollars ($\text{USD}$) in millions is given by $Q_d = 1200 - 2E$, and the quantity supplied is given by $Q_s = 400 + 3E$, where $E$ is the exchange rate in Nigerian Naira per US Dollar ($\text{NGN/USD}$). If an increase in import demand shifts the dollar demand curve upward by $250$ million dollars at every exchange rate level, by how many Naira per Dollar will the equilibrium exchange rate increase?

In many developing economies, a persistent high birth rate creates a demographic structure heavily weighted toward young dependents. How does this high dependency ratio directly impede capital formation and economic development?

A single major mining corporation is the sole buyer of labor services in a remote industrial town. Which market structure best describes this buyer-dominated market?
