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?

Before being simplified, the instructions for computing income tax in Country R were to add 2% of one's annual income to the average of 100 units of Country R's currency and 1% of one's anuual income. Which of the foloowing represents the simplified formula for computing income tax in Country R's currency, for a person whose income is I?

a. 50 + (I/200)
b. 50 + (3I/100)
c. 50 + (I/40)
d. 100 + (I/50)
e. 100 + (3I/100)

Please show/explain your work. This one is so wordy and near the end, I think I drowned in the verbiage.

Which is the simplified formula of income tax, if annual income is I?

I come up with the formula .02I + (100 + .01I)/2. Do not see how this reduces to answer C. Perhaps not enough caffeine this morning. would someone be kind enough to further explain? Thanks. _________________

Ah love this one. Not too hard to solve, just gotta get through wording of the question first.

Whats the diff between B and C?

I = one's annual income 2 percent of ones's annual income = 0.02 of I the average (arithmetic mean) of 100 units of Country R's currency and 1 percent of one's annual income = (100 + 0.01 of I)/2

the simplified formula = 2 percent of ones's annual income + the average (arithmetic mean) of 100 units of Country R's currency and 1 percent of one's annual income

the simplified formula = [0.02 of I + (100 + 0.01 of I)/2] the simplified formula = 50 + I/40 _________________

actually , the prob can be solved very fast , by back solving... but it took me more time to comprehend the meaning of this , thanks to the convoluted langauge....

Thanks for the explanation! I made the mistake of thinking the average of 100 units and 1 % of income was (100units + 1%I/101). The wording confuses me sometimes on hard problems like these!

This is a question from gmat prep 1, I still can't understand it.

Before being simplified, the instructions for computing income tax in Country R were to add 2 percent of ones annual income to the average (arthimetic mean) of 100 units of Country R's currency and 1 percent of one's annual income. Which of the following represents the simplified forumula for computing the income tax, in Country R's, currency for a person in that country whose annual income is I ?

Answer choices:

A) 50 + I / 200 B) 50 + 3I / 100 C 50 + I / 40 D) 100 + I / 50 E 100 + 3I / 100

Also if someone can teach me a better way to copy questions into this forums that would be great as well.

Income of a person is I 2 percent of ones annual income = 2I/100 100 units of Country R's currency = 100 1 percent of one's annual income = I/100 Average of 100 units and 1 percent annual income = 50 + I/200 Sum of average and 2 percent = I/50 + 50 + I/200 = 50 + 5I/200 = 50 + I/40 So answer is C.
