单选题 The regular price of a certain car is $10,000. If the price is discounted by 20 percent during the first week and the reduced price is then discounted by 5 percent during the next week, how much money could one have saved by purchasing this kind of car at the price now rather than at the regular price?
【正确答案】 E
【答案解析】设原先的价格是x，那么第一次打折后是0.8x，第二次打折后是0.8x×0.95=0.76x，所以最后折扣是24％，因此客户能够节省$2400。正确答案为E。
