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
the price of green-tagged trousers=1/2 the original price (10 dollars each) = 5 dollars each
the price of yellow-tagged shirt = 3/4 the original price (16 dollars) = 12 dollars (1/4 off就是7.5折)
全部展开
the price of green-tagged trousers=1/2 the original price (10 dollars each) = 5 dollars each
the price of yellow-tagged shirt = 3/4 the original price (16 dollars) = 12 dollars (1/4 off就是7.5折)
so, total= 2 green-tagged trousers + 1 yellow-tagged shirt = 2*5 + 12= 22 dollars
收起
10*2*0.5+0.75*16=22 0.75，0.5表示打折
he spent 22 dollars for his trousers and shirt
two green-tagged trousers =2*5=10 dollars
one yellow-tagged shirt =16*4/3=12 dollars
