3.(GWD5-28)Last Sunday a certain store sold copies of Newspaper A for $1.00 each and copies of Newspaper B for $1.25 each, and the store sold no other newspapers that day. If r percent of the store’s revenues from newspaper sales was from Newspaper A and if p percent of the newspapers that the store sold were copies of newspaper B, which of the following expresses r in terms of p?
A. 100p / (125 – p)
B. 150p / (250 – p)
C. 300p / (375 – p)
D. 400p / (500 – p)
E. 500p / (625 – p)

不太理解这里的revenue是销量还是总销售收入啊。。。

我的理解Revenue=sales*price的意思吧，直接附上网上的讨论link如下，感觉这个题目最后一个条件该是A不是B
