The price of apples decreases from USD 2.00 per kilogram to USD 1.82 per kilogram, causing the quantity demanded to increase from 100 kilograms to 118 kilograms. Calculate the price elasticity of demand for apples and determine if the demand is elastic, inelastic, or unit elastic.
Price changed by −9%, quantity changed by 18%, so the elasticity is 18%/(−9%)=−2.0.
