OG(11th)DS -Q92

A certain group of care 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) sixty more cars wersold than expected, so that the total amount actually donated was $28,000.

The answer is C

我的答案是B，因為(2)已經說了the total amount ACTUALLY donated was $28,000.為什麼我的想法不對呢？謝謝

新年快樂

題目問的是 "expected" 而不是 "ACTUALLY"

對不起 ...我真的轉不過來...
都已經說了 是可以確定捐這麼多錢了
為什麼還不對呢?

同clbb的說法
題目要求的是預期捐款金額

答案(1)
預期車輛500台
故可設預期捐款金額500X元

答案(2)
僅說實際比預期之車輛多60台,其捐款為28,000元
所以是>>>>預期捐款金額+60X=28,000


所以答案一定要2個公式一起解才能知道預期捐款金額喔~
