All four presses operate differently and are of different sizes. Currently the rm has a contract to produce three products. The contract calls for 400 units of product 1; 570 units of product 2; and 320 units of product 3. The time [in minutes] required for each product to be produced on each machine is as follows: Product 1 1 35 2 40 3 38 Machine 1 is available for 150 hours, machine 2 for 240 hours, machine 3 for 200 hours, and machine 4 for 250 hours. The products also result in different prots, according to the machine they are produced on, because of time, waste, and operating cost. The prot per unit per machine for each product is sumlnarized as follows: Machine 1 2 3 4 1 P78 P78 P82 P79 2 67 89 92 63 3 B4 8 1 90 58 The company wants to know how many units of each product to produce on each machine in order to maximize prot.
