(E) 95% 95%

Answer

Correct choice: (A)

正确答案：（A）

Solution

Answer (A): For the jacket, 40% of \$80 is a savings of \$32. For the shirt, 55% of \$40 is a savings of \$22. The total savings is \$32 + \$22 = \$54. The total of the original prices is \$120. Thus, \$54/\$120 = 0.45 = 45%.

答案（A）：对于夹克，\$80 的 40% 折扣省下 \$32。对于衬衫，\$40 的 55% 折扣省下 \$22。总共节省 \$32 + \$22 = \$54。原价总和为 \$120。因此，\$54/\$120 = 0.45 = 45%。
