Type5 数字计算题 — 例题5

答案与详细解析

正确答案：B

听力原文：

W: Our meal itself was $60. After adding the tax, the total amount comes to 70. Should we pay that?

M: It would be rude if we didn't tip here. For good service, I usually give 20 percent of the original bill, without the tax included.

重点句翻译

Our meal itself was $60. After adding the tax, the total amount comes to 70.

Trans.: 餐费本身是60美元，加上税费后，总额达到70美元。

For good service, I usually give 20 percent of the original bill, without the tax included.

Trans.: 服务好的话，我通常按照不含税的原始账单金额的20%给小费。

分析

根据对话梳理金额计算逻辑：饭菜原价（原始账单）为60美元，含税合计70美元；男士说明服务良好时，小费按 "without the tax included"（不含税的原价）的 20% 计算，小费金额：$60 × 20% = 12美元；最终需要支付的总金额=含税账单70美元+小费12美元 = 82美元（注意：本题易错选A选项，A选项是错误把含税70美元当作基数计算小费得出的结果）。因此选择 B 项。
