An appliance manufacturer produces two models of microwave ovens: Gallery and NeoChef. Both models require fabrication and assembly work, each Gallery uses four hours of fabrication and two hours of assembly, and each NeoChef uses two hours of fabrication and six hours of assembly. There are 600 assembly hours available this week and 480 hours of fabrication. Each Gallery contributes $46 to profits, and each NeoChef contributes $30 to profits. What quantities of Gallery and NeoChef will maximize profits? Develop a linear optimization model to select an optimal production plan. Construct a linear program to solve the appliance manufacturer's problem. [6] What are the decision variables and what do they represent? [7] State the objective function as a mathematical expression [8] State all of the constraints using mathematical expressions.
