The computer solution is shown below.
For the coming production period, the company has 240 fan motors, 340 cooling coils, and 2,600 hours of manufacturing time available. How many economy
models (E), standard models (S), and deluxe models (D) should the company produce in order to maximize profit? The linear programming model for the
problem is as follows:
