At a fruit stand yesterday, the price of each apple was $0.10 more than the price of each orange. What was the total revenue from the sale of oranges at the fruit stand yesterday?
(1) The number of oranges sold at the fruit stand
yesterday was 5 more than the number of
apples.
(2) The total revenue from the sale of apples at the fruit stand yesterday was $15.00
这道题答案给的是C, 可我怎么算也是两个未知数啊,急求各位牛牛了
同问...
做不出来C
我选E
答案给的是C。。。有NN算出来么?我算不出啊。。。
xy=15
(x-0.1)(y+5)=?
似乎算不出啊
我觉得是答案错误。
这个题目最少也要两个未知数:orange的单价和数量
列方程最后出现单独的 有关orange单价和数量的式子,分别不知道这两个未知数的值,所以revenue没法算出来。
应该是E的。
这套题答案错得特别多 太恶心了 搞得我对答案时心都凉了一半!
