If the current price of each towel were to be increased by$1, 10 fewer of the towels could be bought for $120, excluding sales tax. What is the current price of each towel? 这道题 我没看懂,for 120$ 到底是什么意思 谢谢大牛指点~~作者: gtyshr 时间: 2011-4-14 09:50

意思是,如果现在每条毛巾长一块钱,120块能买到的毛巾数就少了10条。比如原来120元能买15条,现在只能5条。作者: gtyshr 时间: 2011-4-14 09:57
