Given the following information set up the problem in a transportation table and solve for the minimum-cost plan: PERIOD 1 2 3 Demand 550 700 750 Capacity Regular 500 500 500 Overtime 50 50 50 Subcontract 120 120 100 Beginning inventory 100 Costs Regular time $ 62 per unit Overtime $ 82 per unit Subcontract $ 96 per unit Inventory carrying cost $ 4 per unit Back-order cost $ 3 per unit per month Suppose that regular-time capacity will be reduced to 440 units in period 3 to accommodate a company wide safety inspection of equipment. An inventory carrying cost is $4 per unit per period. What will the additional cost of the optimal plan be? (Omit the "$" sign in your response.) Additional cost $
