38.24 - 25.47 = 12.77

12.77 / 38.24 X 100 = 1277 /38.24 = 33.394351 %

ANSWER 33.4 % (approx)

33.4 Percent

decrease = 38.24 - 25.47 = $12.77

percentage decrease = 12.77/38.24 ≅ 0.334 = 33.4%

The formula for percentage change is:

(new - old) / old * 100%

new = 25.47

old = 38.24

(25.47 - 38.24) / 38.24 * 100%

= -12.77 / 38.24 * 100%

≈ -0.334 * 100%

≈ -33.4% (move the decimal point two places to the right)

Notice, we got a negative number which means a percentage decrease. So you would write "a decrease of 33.4%".

This same formula works for a percentage increase, just that the new number will be bigger than the old number so you'll get a positive percentage change.

Answer:

A decrease of about 33.4%

(100)(25.47-38.24) / 38.24 = 100(-12.77) / 38.24 = -33.39 percent, a 33.39 percent decrease.
