75.   A certain group of car dealerships agreed to donate x dollars to a Red Cross chapter for each car sold during a 30-day period.  What was the total amount that was expected to be donated?

(1)  A total of 500 cars were expected to be sold.

(2)  60 more cars were sold than expected, so that the total amount actually donated was $28,000.

C

不过这个不是问expected to be donated吗？我选了a, 希望大家帮忙看下

这是我模考的时候遇到的

这道题是说每辆车捐献 x dollar

A 只能知道expect 的车数量

合并起来的话就可以知道560辆车一共捐献了28000元除一下得到x的值

我以为500x就完了，考试考傻了

谢谢啊
