Model-G loudspeaker systems are also shipped to the three warehouses-A, B, and C-whose minimum monthly requirements are 500, 400, and 400 systems, respectively. Shipping costs from plant I to warehouse A, warehouse B, and warehouse C are $16, $20, and $22 per loudspeaker system, respectively, and shipping costs from plant II to each of these warehouses are $18, $16, and $14, respectively.
