A merchant purchased a jacket for $60 and then determined a selling price that equalled the purchase price of the jacket plus a markup that was 25 percent of the selling price. During a sale, the merchant discounted the selling price by 20 percent and sold the jacket. What was the merchant's gross profit on this sale?

答案是$4

不能理解

一个买卖人花60块钱买了个Jacket，想加卖价的25%把它卖出去（注意是他定的selling price的价格而不是purchase的价格的25%)

结果出售的时候由于某种原因打折20%，就是八折，售价的20%

问total profit

设他定的售价为x

x=60+25%x

x=80

然后打了8折，就是卖了64块

利润为4
