The answer is A, 10%. :)

Answer 2

A. 10%

Explanation:

percent change = (new number - old number)/(old number) * 100%

The new number is the increased wage, $8.25, and the old number is the original wage, $7.50.

percent change = ($8.25 - $7.50)/($7.50) * 100%

percent change = ($0.75)/($7.50) * 100%

percent change = 0.1 * 100%

percent change = 10%

Since the percent change is a positive number, it is a percent increase.

The percent increase was 10%.

Answer: A. 10%
