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 and 1 percnt of one's annual income. Which of the following represents the simplified formula for computing the income tax, in Country R's currency, for a person in that country whose annual income is I?
50+I/200
50+3I/100
50+I/40
100+I/50
100+3I/100
那段方程的描述看不懂。。。。the average(arithmetic mean) of 100 units of Country R这到底是虾米东西。。。。还有一个礼拜考试了。。。救命啊啊啊~~~~
顺便求真相：真的换题库啦？~
