(A) $81.00 81.00美元

(D) $82.08 82.08美元

(E) $82.40 82.40美元

Answer

Correct choice: (A)

正确答案：（A）

Solution

The 20% discount lowers the price to $80. Then the $5 coupon reduces the price to $75. The sales tax is 8% of $75, or 0.08 × 75 = 6. Thus, the final cost is 75 + 6 = 81.00.

20%折扣后价格降至80美元。然后5美元优惠券减至75美元。销售税是75美元的8%，即 $0.08 \times 75 = 6$。因此，最终费用是 $75 + 6 = 81.00$ 美元。
