V2【alextan2010】印象最深刻,因为一直读不懂。说一个商品的利润有30%的成本和24% from cost of changing selling price组成,然后sellingprice现在是$274而成本没有变,问之前的selling price是多少?答案有180 190多 200多,我乱选了190。(害我出了一身冷汗,好紧张,后面时间少了)难道是JJ176?
V1 的话很明确啊。 英文应该是这样 。 A product's profit had been 12% of total cost, however, recently it had increased to 30% of total cost at the price of $292, assuming cost did not change, what was the original price?
