Consider the market for the Ford F-150 pickup truck.The demand for the F-150 is given by Q^d = 25000 - 0.9P + 0.75P_S + 1.2I, where Q^d is the quantity ofF-150s demanded (in 000s), P is the price of an F-150 in dollars, P_S is the price of a Chevrolet Silverado truck, in dollars, and I is average consumer disposable income.The supply of F-150s is given by Q^s = -12000 + 1.4P - 1.6P_t, where Q^s is the quantity of F-150s supplied (in 000s) and P_t is the price of a set of tires for each pickup truck. Suppose, initially:P_S = $32,000, I = $16,000, and P_t = $800.Use this information to answer the question.Suppose the market price (P) of F-150s were $36,000.How many F-150s would be demanded?How many supplied?

What are the steps to figure out Qs and Qd?
