Show transcribed image text A company manufactures three products A, B, and C. Each unit of product A requires 1 hour of engineering service, 10 hours of direct labor, and 3 pounds of material. To produce one unit of product B requires 2 hours of engineering, 4 hours of direct labor, and 2 pounds of material. Each unit of product C requires 1 hour of engineering, 5 hours of direct labor, and 1 pound of material. There are 100 hours of engineering, 700 hours of labor, and 400 pounds of materials available. The cost of production is a nonlinear function of the quantity produced as shown below: (If 60 units of A are made, the first 40 units cost $10 per unit and the remaining 20 units cost $9 per unit.) Formulate a mixed integer program to determine the minimum-cost production schedule.
