Before being simplified, the instructions for computing income tax in Country R were to add 2 percent f 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, or a person in that country whose annual income is I?

A 50 + I/200
B 50 + 3I/100
C 50 + I/4
D 100 + I/50
E 100 + 3I/100

please, help !!!

answer C

sorry mike,

answer C = 50 + I/40

and NOT C = 50 + I/4 neither C = 5 + I/40

can you explain how did you get C?

thanks!!

2 percent of one's annual income = I *2/100

average (arithmetic mean) of 100 units of Country R's currency and 1 percent of one's annual income


[100 + I/100 ]/2 = 50 +I/200

Now Tax = I*2/100 +{ 50 + I/200 }

= 50 + I/40

Thanks for the explanation. Questions about taxes put me on edge, especially in April! (tax season in US)

2 percent of annual income = I *2/100

average arithmetic mean and annual income


(100 + I/100 )/2 = 50 +I/200

Now Tax = I*2/100 +{ 50 + I/200 }

= 50 + I/40
