During the next production period, the labor-hours available are 250 in department
A, 350 in department B, and 180 in department C. The profit contributions per unit
are $29 for product1, $25 for product 2, and $32 for product 3.
a) Formulate a linear programming model for maximizing total profit contribution?
b) Solve the linear program formulated in part (a) using excel. How much of each
product should be produced, and what is the projected total profit contribution?
