  1. $64\$64Answer
  2. B
    $16\$16
  3. C
    $96\$96
  4. D
    $60\$60
  5. E
    $72\$72

Answer

$64\$64
To find the sale price after a 20%20\% discount, calculate 20%20\% of the original price (0.20×80=160.20 \times 80 = 16) and subtract it from the original price (8016=6480 - 16 = 64). Alternatively, multiply the original price by (10.20)=0.80(1 - 0.20) = 0.80, giving 80×0.80=6480 \times 0.80 = 64.

Step-by-Step Solution

1
Calculate the dollar value of the discount
Discount=0.20×$80=$16\text{Discount} = 0.20 \times \$80 = \$16
A 20%20\% discount means reducing the original price by 2020 hundredths of its total value.
2
Subtract the discount from the original price
Sale Price=$80$16=$64\text{Sale Price} = \$80 - \$16 = \$64
The final sale price equals the original price minus the discount amount.
