182题里有一句话是这样的:A photographer dealer ordered 60 model X cameras to be sold for$250 each, which represents a 20 percent make up over the dealer's initial cost for each camera of the cameras ordered.
我的理解是250里面包括了20%的成本,这样每一个的成本就是20%*250. 可是答案上的解释是cost=250/1.2,看来我的理解和答案不一样,那么其中which represents a 20 percent make up over the dealer's initial cost for each camera of the cameras ordered到底是如何翻译的呢?
