  2. B
    $20\$20
  3. C
    $55\$55
  4. D
    $100\$100

Answer

The final sale price of the backpack is $60\$60.
The correct answer is found by first calculating 25%25\% of $80\$80, which is $20\$20. Since it is a discount, this $20\$20 is subtracted from the original $80\$80 price, resulting in a final sale price of $60\$60. Alternatively, a 25%25\% discount means the buyer pays 75%75\% of the original price, and 0.75×$80=$600.75 \times \$80 = \$60.

Step-by-Step Solution

1
Calculate the amount of the discount.
0.25×$80=$200.25 \times \$80 = \$20
To find the discount amount, multiply the original price by the decimal form of the percentage (25%=0.2525\% = 0.25).
2
Subtract the discount from the original price.
$80−$20=$60\$80 - \$20 = \$60
The final sale price is the original price minus the discount amount.
