Hart Manufacturing makes three products. Each product requires manufacturing operations in three departments: A, B, and C. The labor-hour requirements, by department, are as
follows:

(a) Formulate a linear programming model for maximizing total profit contribution.
If the constant is "1" it must be entered in the box. If required, round your answers to two decimal places.
Let P₁ = units of product i produced
$
During the next production period the labor-hours available are 450 in department A, 350 in department B, and 50 in department C. The profit contributions per unit are $25 for product
1, $28 for product 2, and $30 for product 3.

program that takes setup costs provided in part (c) into account. Management also stated that we should not consider making more than 175 units of product 1, 150 units of
product 2, or 140 units of product 3. What are the new objective function and additional equation constraints?
