What is the percent increase when a price rises from $40 to $52?

Explanation:
Percent change is found by comparing how much the value has increased to the original amount. The price goes from 40 to 52, so the increase is 52 − 40 = 12. Divide the increase by the original price: 12/40 = 0.30. Multiply by 100 to get a percentage: 0.30 × 100 = 30%. So the price increased by 30%.
