The warehouse can hold a maximum of 5,500 units in inventory at the end of each month. Management wants to keep at least 1,500 units in inventory as safety stock to balance variations in demand. To maintain stable workforce, the company wants to produce no less than one half of its maximum production capacity each month. The accounting department estimates that the cost of carrying a unit in any month is approximately equal to 1.5% of the unit production cost in the same month. ABX estimates the number of units carried in inventory each month by averaging the beginning and ending inventory for each month.

There are 3,600 units currently in inventory. ABX wants to identify the production and inventory plan for the next six months that will meet the expected demand each month while minimizing production and inventory costs.

What is the best total production and inventory cost? (Do not include dollar sign)
