Question 2: After a careful statistical analysis, the Chidester Company concludes the demand function for its product is: Q = 500 - 3P + 2Pr + 0.1I where Q is the quantity demanded of its product, P is the price of its product, Pr is the price of its rival's product, and I is per capita disposable income (in dollars). At present, P = $10, Pr = $20, and I = $6,000. a. What is the price elasticity of demand for the firm's product? b. What is the income elasticity of demand for the firm's product? c. What is the cross- price elasticity of demand between its product and its rival's product?
