19-2. Table 19-2 on page 424 indicates that the shortrun price elasticity of demand for tires is 0.9. If an increase in the price of petroleum (used in producing tires) causes the market prices of tires to rise from $50 to $60, by what percentage would you expect the quantity of tires demanded to change? 19-3. The diagram below depicts the demand curve for “miniburgers” in a local fast-food market. Use the information in this diagram to answer the questions that follow. a. What is the price elasticity of demand along the range of the demand curve between a price of $0.20 per miniburger and a price of $0.40 per miniburger? Is demand elastic or inelastic over this range? b. What is the price elasticity of demand along the range of the demand curve between a price of $0.80 per miniburger and a price of $1.20 per miniburger? Is demand elastic or inelastic over this range? c. What is the price elasticity of demand along the range of the demand curve between a price of $1.60 per miniburger and a price of $1.80 per miniburger? Is demand elastic or inelastic over this range?
