A toy store regularly sells all stock at a discount of20 percent to 40 percent. If an additional 25 percentwere deducted from the discount price during aspecial sale, what would be the lowest possible priceof a toy costing $16 before any discount? 那题目最后的before any discount是怎么回事儿?感觉是:一个价值16美圆的玩具在没有任何折扣 之前最低的价格是多少? 但是答案每个都比16美元少啊??
