问题 单项选择题

An employee is paid 1.5 times the regular hourly rate for each hour worked in excess of 40 hours per week, excluding Sunday, and 2 times the regular hourly rate for each hour worked on Sunday. How much was the employee paid last week ?()
(1)The employee’s regular hourly rate is $10.
(2)Last week the employee worked a total of 54 hours but did not work more than 8 hours on any day.

A.条件(1)充分,但条件(2)不充分.

B.条件(2)充分,但条件(1)不充分.

C.条件(1)和(2)单独都不充分,但条件(1)和条件(2)联合起来充分.

D.条件(1)充分,条件(2)也充分.

E.条件(1)和条件(2)单独都不充分,条件(1)和条件(2)联合起来也不充分.

答案

参考答案:E

解析:

(1)不充分,因为(1)不知道工作的时间是多少;(2)也不充分,因为不知道每小时的工资是多少;由(2)可知,该雇员上周一定是工作了7天,在每天不超过8小时的情况下分配这54小时有两种分法:第一种分法是其中有一天工作了6小时,其余每天都工作了8小时;第二种分法是其中有两天工作了7小时,其余的每天都工作了6小时,但因为星期天每小时的工资和平常是不一样的,且又不知道究竟是哪一天工作了6小时或7小时,所以(1)+(2)也无法判断该雇员上星期得了多少钱。
