Question

The price of a gallon of unleaded gas has dropped to $2.78 today. Yesterday’s price was $2.85. Find the percentage decrease. Round your answer to the nearest tenth of a percent.

Answer 1

Percent decrease =

(difference in prices)/(original price) × 100

(2.85 - 2.78)/2.85 × 100

= (0.07)/2.85 ×100 ≈ 2.5%
