Her operations manager is considering a new plan, which begins in January with 200 units on hand and ends with zero inventory. Stockout cost of lost sales is $125 per unit. Inventory holding cost is $25 per unit per month. Ignore any idle-time costs. The plan is called plan B.

Plan B: Produce at a constant rate of 1,500 units per month, which will meet minimum demands. Then use subcontracting, with additional units at a premium price of $80 per unit. Subcontracting capacity is limited to 600 units per month. Evaluate this plan by computing the costs for January through august.
