At a certain restaurant, if each hamburger costs the same amount, what is the cost, excluding sales tax, of 1 hamburger?

 

(1)  The total cost, including a 6 percent sales tax, is $4.77 for 3 hamburgers.

 

(2)  The total cost, including a 6 percent sales tax, is less than $6.50 for 4 hamburgers.

答案是A,我认为 是 E,因为我们并不知道 sales tax是多少?

路过..不就是4.77/1.06再/3么?...

shirley8707

难道 销售税=成本（除销售税）*6%

including a 6 percent sales tax 这个就是我的疑惑。请好心人再帮我解释一下。谢谢。

The total cost （of hamburgers）……指花费的意思

MM，虽然你叫我牛人我很高兴但我还是要谦虚我真的不是牛人而且这道题实在太简单了啊……

看来还是理解的问题。不过以前看ted回答，都很清楚呀。而且有意到很难的题目你都解释得很好。所以。。
