题目给出了一个人要交的tax的计算方式:
add 2% of one's annual income to the average (arithmetic mean) of 100 units of the country's currency and 1% of his annual income
问如果这个人的annual income 是 X,那么这个人要交多少tax?
答案是50+X/40
我做这题的时候看了几遍题目,还是没有完全理解它的意思,主要是不明白add 2% of one's annual income to the average (arithmetic mean) of 100 units of the country's currency是什么意思,求助高人指点~~~
举报
2%的年收入 加上 (100个单位的货币,就是100块钱,和1%年收入的平均数)
2%x+(100+1%x)/2
原来是这样 了解啦~~
谢谢~~
