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 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

add(2%of one's annual income) to (average of((100units))and((1%of annual income)))
这个句子太长，要找 add a to b 以及average of a and b
