E. $65.00 OA E Source: Official Guide The original average salary is 3,250/5 =$650.

If each of the 5 salaries is to increase by 10%, the new sum of the salaries will also increase by 10%. Thus, the new sum is:

0.1 x 3,250 + 3,250 = 325 + 3,250 = $3,575 Thus, the new average salary is 3575/5 =$715, and each salary increases by 715 - 650 = $65. Alternate Solution: If each of the salaries is increased by 10%, then the average salary will increase by 10% as well. The original average salary is 3,250/5 =$650. Thus, a 10% salary increase is 650 x 0.10 = $65 per person.

E. $65.00 Since each salary increases by 10%, the sum increases by 10%. 10% of 3250 = 325. Average increase per employee = (total increase)/(number of employees) = 325/5 = 65.
