please solve part d and e only

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. Department Product 1 Product 2 Product 3 A 1.50 3.00 2.00 B 2.00 1.00 2.50 0.25 0.25 0.25 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 $24 for product 1, $27 for product 2, and $29 for product 3. (a) Formulate a linear programming model for maximizing total profit contribution. (Let P = units of product i produced, for i = 1, 2, 3.) Max 24P2 + 27P, + 29P s.t.

How much of each product should be produced, and what is the projected total profit contribution (in dollars)?

Formulate a mixed-integer linear program that takes setup costs into account. Management also stated that we should not consider making more than 145 units of product 1, 155 units of product 2, or 165 units of product 3. (Let P, = units of product i produced and y be the 0-1 variable that is one if any quantity of product iis produced and zero otherwise, for i = 1, 2, 3.) What is the objective function of the mixed-integer linear program? Max In addition to the constraints from part (a), what other constraints should be added to the mixed-integer linear program? s.t. units of Product 1 produced units of Product 2 produced units of Product 3 produced Par P2P, 20; V, V2, V3 = 0,1 (e) Solve the mixed-integer linear program formulated in part (d).
