1. Exercise 5.1 The forecasting staff for the Prizer Corporation has developed a model to predict sales of its air-cushioned-ride snowmobiles. The model specifies that sales, S, vary jointly with disposable personal income, Y, and the population between ages 15 and 40,Z, and inversely with the price of the snowmobiles, P. Based on past data, the best estimate of this relationship is: where k has been estimated (from past data) to equal 100 If Y $13,000, Z- $1,200, and P...
