讨论gwd第八套两道答案疑惑题

 Q6: Sue's monthly earnings consist of a monthly salary and a 4 percent commission on the portion of her monthly sales that is in excess of $2,000. If Sue's monthly salary was the same in July as in August, how much greater were her sales in July than August?

1: Sue's monthly earnings were $3,620 in July and $3,580 in August

2: Sue's monthly salary was $3,500 in July and in August  

(Answer is A. 我觉得答案错了，我选c。 如果她的monthly salary就等于$3，580，那她在八月的sales就不能确定了，是小于$2.000的任何一个数，答案只考虑了salary小于$3,580的情况）

Q33: If the volume of a small container is 14,520 cubic millimeters, what is the volume of the container in cubic centimeters? ( 1 millimeter = 0.1 centimeter)

A: 0.1452    B: 1.452     C: 14.52     D: 145.2    E: 1,452    (Answer is C, 我觉得因该选A吧）
