Question

Help with b please I don’t understand it

Answer 1

This is a 25% decrease

Explanation:

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

The new price is 15

The old price is 20

Since the new price is less than the old price, it is a decrease

percent change = (20-15)/20 * 100 %

= 5/20 * 100%

=.25 * 100%

= 25%

This is a 25% decrease
