Given the projected demands for the next six months, prepare a Chase aggregate plan that uses regular time and subcontract. The plan must wind up with no units in ending inventory in period 6. Regular time capacity is 150 units per month. Overtime is $30 per unit and regular time cost is $20 per unit. Beginning inventory is zero. Workers can be re-assigned to other production lines without any additional cost. Month Forecast 1 1 180 2. 130 3 140 4 150 5 5 170 6 150 What is the total cost of the plan
