答案应该是两元，肯定不会错

xbpj 发表于 2007-1-3 16:28:14

赚2块。进来20元，出去18元

zhangwen_c 发表于 2007-1-10 16:19:00

<p>2元,这有什么难度吗？这我可是很有自信。不用怀疑，这和买卖股票有什么区别？</p>

kfskfsk 发表于 2007-1-10 19:04:46

对哦！一共卖了20元。成本一共18元。看偶笨的，只懂得按顺序想事情，见笑啦。谢谢大家啊。

xhcsnow 发表于 2007-1-22 16:39:40

<p>是2元没错啊</p>

晕，又没答案

将一次买卖分为两次来看，每次挣一块，两次就两块了。
