    A. 15%

    Step-by-step 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%
