题目是
Before being simplified, the instructions for computing income tax in Country R were to add 2 percent of one's annual income to the average (arithmetic mean) of 100 units of Country R's currency and 1 percent of one's annual income
Which of the following reprentes the simplified formula for computing the income tax, in Country R's currency, for a person in that Country whose annual income is I?
答案是 50+ I/40
关键是我不太理解 to add 2 percent of one's annual income to the average (arithmetic mean) of 100 units of Country R's currency 的意思,请NN帮忙,谢谢!
这个比较难理解,遇到这种情况看到名词就想定义就好,不用怕
to add……to……就是+,所以写2%AI+
average of就是【()+()】/2 所以是100+1%AI
所以就是2%AI+100+1%AI
谢谢!这下看懂了
