C. 25%
. 33%

Answer 1

A. 15%

Explanation:

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

The new number is the increased area, 25,587.5 sq yd, and the old number is the original area, 22,250 sq yd.

percent change = (25,587.5 sq yd - 22,250 sq yd)/(22,250 sq yd) * 100%

percent change = (3,337.5 sq yd)/(22,250 sq yd) * 100%

percent change = 0.15 * 100%

percent change = 15%

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

The percent increase was 15%.

Answer: A. 15%
