A price increases from 50 to 65. What is the percent increase?

• A. 20%
• B. 15%
• C. 25%
• D. 30%

Answer: (D)

Percent increase is found by comparing the change to the original amount. The price goes from 50 to 65, so the change is 65 − 50 = 15. Relative to the original 50, that change is 15 ÷ 50 = 0.30. Converting to a percentage gives 0.30 × 100 = 30%. So the price increase is 30%.
