3. Determinants of demand The following graph shows the demand curve for sedans in New York City. For simplicity, assume that all sedans are identical and sell for the same price. Initially, the graph shows market demand under the following circumstances: Average household income is $50,000 per year, the price of a gallon of regular unleaded gas is $4 per gallon, and the price of a subway ride is $3.00. Use the graph input tool to help you answer the following questions. You will not be graded on any changes you make to this graph. Note: Once you enter a value in a white field, the graph and any corresponding amounts in each grey field will change accordingly. 40 8 PRICE (Thousands of dollars per sedan) curv 20 O Demand for Sedans Demand 0 100 200 300 400 500 600 700 800 900 QUANTITY (Sedans per month) Graph Input Tool Demand for Sedans Price of a sedan (Thousand of dollars) A decrease in average income causes a leftward Quantity Demanded (Sedans per month) Demand Shifters Average Income (Thousands of dollars) Price of Gas (Dollars per gallon) Price of a Subway Ride (Dollars) 20 450 Consider the graph.

(Hint: Try substituting different values for Average Income in the graph input tool and observing what happens.) Suppose that the price of a subway ride falls from $3.00 to $2.50. Because driving a car and taking the subway are decrease in the price of a subway ride shifts the demand curve for sedans to the ▼ the demand
