25. Cindy bought a sweater for $40 that was priced the week before $50.

The original price is $50 and the new price is $40.

The percent change is calculated as follows:

percent change = [(new value - old value) / old value] x 100%

percent change = [(40 - 50) / 50] x 100%

percent change = (-10/50) x 100%

percent change = -0.2 x 100%

percent change = -20%

Therefore, the percent change is a decrease of 20%.
