SOLUTION

A corporation that had $115.19 billion in profits for the year paid out $230.10 million in employee benefits. Approximately what percent of the profits were the employee benefits? (Note: 1 billion = 10^9)

(A) 50%
(B) 20%
(C) 5%
(D) 2%
(E) 0.2%

We should find the value of \frac{230.10*10^6}{115.19*10^9}\approx{\frac{230*10^6}{115*10^9}}=2*10^{-3}=0.002=0.2%.

Answer: E.

=(2/1000)*100
=0.2%
