Understanding Price Elasticity: How Price Changes Affect Quantity

TLDRPrice elasticity measures the sensitivity of quantity to a change in price. Gasoline has inelastic demand, meaning a small change in price leads to a proportionally smaller change in quantity. Elastic demand occurs when quantity is sensitive to price changes, often due to many substitutes or luxury status. The total revenue test helps determine if demand is elastic or inelastic.
