# Rising Gas Prices – Compounding and Inflation

Alignments to Content Standards: F-LE.A

Inflation is the measure of the annual growth in the price of a good or service, computed as the percentage change in price from the previous year. For example, if the price of gasoline rose from \$2.00 a gallon to \$2.20 per gallon in one year, the inflation rate for gasoline for that year would be $\frac{2.20 - 2.00}{2.00} \times 100 = 10.0$ percent.
