1. Problem 13 in Chapter 1 posed the following situation: A manufacturer of mp3 players is preparing to set the price on a new model. Demand is thought to depend on the price and is represented by the model D = 2,000 - 3P The accounting department estimates that the total costs can be represented by C = 5,000 + 4D You were asked to develop a model for the total profit and implement it on a spreadsheet. Use nonlinear optimization with Solver to find the price that maximizes profit.
