The price of gas is $2.15 / gallon today. Last week it was $2.55 for a gallon of gas. What was the percent change in the price?

15.69% decrease

Step-by-step explanation:

To find the percent change, we take the original price and subtract the new price

2.55 -2.15 = .40

Divide by the original price

.40/2.55

.156862745

Multiply by 100%

15.6862745 %

Since the price went down, this is a decrease

15.69% decrease
