Problem: A manufacturer produces two products, AD1 and AD2. Each unit of AD1 requires 4 hours of fabrication and 2 hours of assembly. Each unit of AD2 requires 2 hours of fabrication and 6 hours of assembly. There are 600 fabrication hours and 480 assembly hours available this week. Each AD1 contributes $40 to profits and each AD2 contributes $30 to profits.
(a) Using linear programming, plot the graph to show feasible solution for AD1 and AD2.
(b) What quantities of AD1 and AD2 will maximize profits?
