还有一个做OG数学时遇到的问题,大概是很愚蠢的问题
P 241
41 The regular price for canned soup was reduced during a sale. How much money could one have saved by purchasign a dozen 7-ounce can of soup at the reduced price rather than at the regular price?
(1) The regular price for the 7-ounce cans was 3 for a dollar.
(2) The reduced price for the 7-ounce cans was 4 for a dollar.
我是选了c,但是不明白3for a dollar 什么意思?reduced price 怎么倒是4 for a dollar.[em01]
