A merchant purchased a jacket for 60 $ and then determined a selling price that equalled the purchased price of the jacket plus a mackup that was 25% of the selling price.during the sale,the merchant discounted the selling price by 20% and then sold the jacket.what was the merchant's gross profit on this sale?4 求详解,谢
答
一个商人花60美元买了一件一夹克,决定在60美元的基础上加上出售价的25%出售.在出售过程中又打了20%的折扣,问商人获利多少?
设出售价为X,则：
60+25%X=X
得X=80
实际出售价为 80-80*20%=64
所以获利为 64-60=4
