Problem 3. The figure below depicts the estimated demand curve for gasoline in Detroit and Chicago. When the price of gasoline is $3/gallon, the total gasoline demand is the same in the two cities (i.e., 1.5 million gallons). Figure 2: Demand for gasoline in Detroit and Chicago Price/gal. DPETROIT 4 froceeeene $3 |ooememme e \\ ! [DCHICAGO 1.5 Quantity (million gallons) a) Can you say which demand curve is more elastic at price $3.00 per gallon? b) Without knowing the mathematical formula for these two demand curves, can you say which demand curve is more elastic at price $4.00 per gallon
