以下是引用喝咖啡的狼在2008-7-4 17:59:00的发言：

Before being simplified, the instructions for computing income tax in Country R were to added 2 percent of one's annual income to the average of 100 units of R's currency and 1 percent of one's annual income, what is the simplified formula for computing the income tax if one's annual income is X?

A 50+ X/200 B 50+3X/100 C 50+X/40 答案选 C 题目压根没看懂。。。。。。

2% x + (100 + 1%x)/2

同样没看懂..

我“斗胆”解释一下子吧~呵呵~好像就是一个公式化简的问题TAX=2%*一个人的annual income+(100 units +1%* annual income这二者的平均值) 化简后就如同三楼同学的解释啦~但是就是始终觉得 100 units of Country R's currency 有点问题呢。。。

有NN能用中文简要解释一下意思吗？

Amelia_21 · 发表于 2008-7-5 23:40:00
