Use the following generalized linear demand relation to answer the next three questions: Qs = 200 - 5P +.004M + 5Pr, where P is the price of good X, M is income, and P, is the price of a related good, R. M = $50,000 and P, = $10 and the supply function is 0. = 150+5P. 1. Good X is and Good R is a a. inferior, complement b. inferior, substitute. c. normal, complement d. normal, substitute 2. Market price and output are, respectively, P= $12 and Q = 150. P = $10 and Q = 200. P = $30 and Q = 300. P =$30 and Q = 175. P = $15 and Q = 225. 3. The price elasticity of demand is -0.25 oso -5 none of the above
