1.Trousers on sale for1/2 price have a green tah.Shirts on sale for 1/4 off have a yellow tag.Stephen bought two green-tagged trousers originally priced at 10 dollars each,and one yellow-tagged shirt orginally priced at 16 dollars How much did he pay for his trousers and shirt?
答
two green-tagged trousers originally priced at 10 dollars each
两条裤子就花了10元钱因为是打半价10*2*1/2=10元
one yellow-tagged shirt orginally priced at 16 dollars
一条衬衫 原价16 花了 16*3/4= 12元
一共是 10+12=22元为什么是乘3//4Shirts on sale for 1/4 off 的意思是减四分之一的价格off 有去掉的意思
