是在prep模考的时候看到的,死活想不明白,特来求助
是关于个人所得税的,假设一个人的年收入是I,关键部分读不懂所以只能上英语了,the instructions for computing income tax in country R were to add 2 percent of one's annual income to the average of 100 units of Country R's currency and 1 percent of one's annual income. 接下来就是要你选择用I表达的这个计算收入税的方程式
答案是50+(I/40),后面一个括号里面就是一个分数,为了区别前面的50,完全不知道思路在哪里,求教
慢慢细读啊~
instructions for computing income tax是计算所的税的方法
add 2 percent of one's annual income to 把2%I加到
the average of 100 units of Country R's currency and 1 percent of one's annual income 100单位货币和1%I的平均值
