A local hardware store is purchasing a bulk wholesale order of industrial shelving. The distributor offers a 20%20\% volume discount on the order. Because the hardware store pays the invoice in full within 10 days, they receive an additional 5%5\% discount on the reduced price. If the hardware store pays $3,420\$3,420 for the shelving (before shipping and taxes), what was the original price of the bulk order?

Cevabı ve açıklamayı göster

Cevap: $4,500\$4,500

Cevap

$4,500\$4,500
The correct answer is found by representing the unknown original price as a variable, applying the 20% discount (multiplying by 0.80), and then applying the 5% discount to that new amount (multiplying by 0.95). Setting the resulting expression (0.76 times the original price) equal to the final price of 3,420anddividingyieldsanoriginalpriceof3,420 and dividing yields an original price of 4,500.

Adım Adım Çözüm

1
Set up an equation representing the first discount.
Let the original price be PP. A 20%20\% discount means the price becomes 100%−20%=80%100\% - 20\% = 80\% of the original price, or 0.80P0.80P.
The volume discount is applied to the starting original price.
2
Apply the second successive discount to the result of the first.
An additional 5%5\% discount on the reduced price means the hardware store pays 100%−5%=95%100\% - 5\% = 95\% of that reduced price. This gives 0.95×0.80P=0.76P0.95 \times 0.80P = 0.76P.
Successive discounts are calculated based on the new, already-discounted price, not the original price.
3
Solve for the original price PP.
Set the expression equal to the final paid amount: 0.76P=34200.76P = 3420. Divide both sides by 0.760.76 to find P=$4,500P = \$4,500.
This isolates PP to determine the starting value before any discounts were applied.

A musician is purchasing a new drum kit for $1,200\$1,200 and a set of cymbals for $400\$400. The music store is running a promotion that offers a 15%15\% discount on the total purchase if it exceeds $1,000\$1,000. After the discount is applied, a 6%6\% state sales tax is added to the sale price.

Based on this information, the total amount saved from the discount is $\$,andthefinalamountpaidaftertaxis, and the final amount paid after tax is \$$.
Cevabı ve açıklamayı göster

Cevap

The discount amount is $240\$240, and the final total paid is $1,441.60\$1,441.60.
The solution requires finding the total original price of $1,600\$1,600. The 15%15\% discount on this amount is $240\$240, leaving a sale price of $1,360\$1,360. Finally, calculating a 6%6\% sales tax on $1,360\$1,360 adds $81.60\$81.60, bringing the final total to $1,441.60\$1,441.60.

Adım Adım Çözüm

1
Calculate the total original price of the items.
$1,200+$400=$1,600\$1,200 + \$400 = \$1,600
To find the base amount before any discounts are applied.
2
Calculate the discount amount.
15%15\% of $1,600=0.15×1600=$240\$1,600 = 0.15 \times 1600 = \$240
Since the purchase exceeds $1,000\$1,000, the 15%15\% discount applies to the total original price. This provides the first missing value.
3
Calculate the sale price before tax.
$1,600−$240=$1,360\$1,600 - \$240 = \$1,360
Subtracting the discount from the original price gives the taxable amount.
4
Calculate the sales tax.
6%6\% of $1,360=0.06×1360=$81.60\$1,360 = 0.06 \times 1360 = \$81.60
Sales tax is calculated based on the discounted sale price.
5
Calculate the final total paid.
$1,360+$81.60=$1,441.60\$1,360 + \$81.60 = \$1,441.60
Adding the sales tax to the sale price yields the final cost. This provides the second missing value.

A fleet manager is purchasing a replacement heavy-duty transmission. The original price of the transmission is $3,200\$3,200. The supplier offers a 15%15\% commercial discount, and an additional 5%5\% discount off the reduced price if the invoice is paid within 1010 days. If the manager pays the invoice on the same day, what is the final price of the transmission before any taxes?

Cevabı ve açıklamayı göster

Cevap: $2,584\$2,584

Cevap

The final price of the transmission is $2,584\$2,584.
The correct answer accurately calculates the successive discounts step by step. First, a 15%15\% discount on $3,200\$3,200 saves $480\$480, bringing the price to $2,720\$2,720. Then, a 5%5\% discount on the new price of $2,720\$2,720 saves $136\$136, resulting in a final price of $2,584\$2,584.

Adım Adım Çözüm

1
Calculate the price after the first discount of 15%15\%.
$3,200×0.15=$480\$3,200 \times 0.15 = \$480 in savings. The new price is $3,200−$480=$2,720\$3,200 - \$480 = \$2,720.
The commercial discount is applied to the original price of the item.
2
Calculate the final price after the second discount of 5%5\%.
$2,720×0.05=$136\$2,720 \times 0.05 = \$136 in savings. The final price is $2,720−$136=$2,584\$2,720 - \$136 = \$2,584.
Successive (chain) discounts are always applied to the previously reduced price, not the original price.

A commercial photographer is purchasing a new studio lighting kit. The original retail price of the kit is $1,200\$1,200. The camera supply store is currently offering a 25%25\% seasonal discount on all studio equipment. In addition, the photographer receives a 10%10\% professional discount, which is applied to the already reduced price. What is the final price of the lighting kit before sales tax?

Cevabı ve açıklamayı göster

Cevap: 810

Cevap

The final price of the lighting kit is $810\$810.
The correct calculation requires applying the first discount to find a new subtotal, and then applying the second discount to that new subtotal. Applying 25%25\% off $1,200\$1,200 yields $900\$900. Applying the 10%10\% professional discount to the new base of $900\$900 reduces the price by another $90\$90, resulting in a final price of $810\$810.

Adım Adım Çözüm

1
Calculate the first discount amount.
25%25\% of $1,200\$1,200 is $300\$300.
The seasonal discount applies to the original retail price.
2
Find the intermediate reduced price.
$1,200−$300=$900\$1,200 - \$300 = \$900.
Subtracting the first discount gives the new base price before the second discount.
3
Calculate the second discount amount.
10%10\% of $900\$900 is $90\$90.
The professional discount applies to the already reduced price, not the original price.
4
Determine the final price.
$900−$90=$810\$900 - \$90 = \$810.
Subtracting the second discount from the intermediate price gives the final amount paid.

A restaurant manager orders a bulk supply of premium cooking oil. The invoice shows a final cost of $510\$510 after a 15%15\% wholesale discount was applied to the standard price. What was the original standard price of the bulk supply before the discount?

Cevabı ve açıklamayı göster

Cevap: $600.00\$600.00

Cevap

The original standard price of the bulk supply was $600.00.
The final cost of 510represents85510 represents 85% of the original price, because a 15% discount was subtracted (100% - 15% = 85%). To find the original whole amount, divide the part by the percentage as a decimal: 510 \div 0.85 = \600600.

Adım Adım Çözüm

1
Determine the percentage of the original price that the final cost represents.
Since a 15%15\% discount was applied, the manager paid 100%−15%=85%100\% - 15\% = 85\% of the original price.
The final discounted price represents the remainder of the original cost after the discount is subtracted.
2
Set up an equation and solve for the original price.
Let xx be the original price. The equation is 0.85x=5100.85x = 510. Solving for xx gives x=510÷0.85=600x = 510 \div 0.85 = 600.
Dividing the part (the discounted price) by its equivalent percentage (expressed as a decimal) gives the whole original amount.

Cevap: 13680

Cevap

13680
The correct total is found by first determining the initial total order value ($18,000\$18,000), reducing it by the initial 20%20\% discount to find the new subtotal ($14,400\$14,400), and then reducing that subtotal by the additional 5%5\% discount to arrive at the final cost ($13,680\$13,680).

Adım Adım Çözüm

1
Calculate the total original price of the 4 servers.
4×$4,500=$18,0004 \times \$4,500 = \$18,000
The discounts apply to the total order, so the total initial cost must be determined first.
2
Apply the 20% corporate discount to the total original price.
\$18,000 \times 0.20 = \$3,600 \text{ discount; } \$18,000 - \$3,600 = \$14,400
The first discount reduces the total cost before any other discounts are considered.
3
Apply the 5% early-payment discount to the new, reduced price.
\$14,400 \times 0.05 = \$720 \text{ discount; } \$14,400 - \$720 = \$13,680

Cevabı ve açıklamayı göster

Cevap

The original price of the diagnostic tool was $1,200.
To find the original price, we must reverse each transaction step starting from the final price. First, we remove the 6%6\% sales tax by dividing $864.96\$864.96 by 1.061.06 to get $816.00\$816.00. Next, we reverse the 15%15\% discount by dividing $816.00\$816.00 by 0.850.85 (since the discounted price represents 85%85\% of the previous price), resulting in $960.00\$960.00. Finally, we reverse the 20%20\% clearance discount by dividing $960.00\$960.00 by 0.800.80, which yields the original price of $1,200.00\$1,200.00.

Adım Adım Çözüm

1
Remove the 6%6\% sales tax from the final total to find the price of the tool after all discounts.
$864.96÷1.06=$816.00\$864.96 \div 1.06 = \$816.00
The final total represents 106%106\% of the discounted price. Dividing by 1.061.06 mathematically reverses the tax application.
2
Reverse the 15%15\% promotional discount to find the initial clearance price.
$816.00÷0.85=$960.00\$816.00 \div 0.85 = \$960.00
The price after the promo code was applied represents 85%85\% (100%−15%100\% - 15\%) of the clearance price. Dividing by 0.850.85 finds the value before this second discount.
3
Reverse the initial 20%20\% clearance markdown to determine the original price.
$960.00÷0.80=$1,200.00\$960.00 \div 0.80 = \$1,200.00
The clearance price represents 80%80\% (100%−20%100\% - 20\%) of the original price. Dividing by 0.800.80 finds the starting value.
