Production using overtime (OT) hours will be available only at the Decatur plant; - The tables below show the production costs per unit at each plant (RT and/or OT), production capacities (RT and/or OT) for each plant, and the shipping costs per unit for each shipping lane between a plant and a warehouse (as provided already in Problem 6).
