H&C Corporation is preparing an aggregate production plan for widgets for the next four months. The company's expected monthly demand is given in the following chart. The company will have 50 widgets in inventory at the beginning of the first month and wishes to maintain at least that number at the end of each month. Following is other critical data:

Production cost per unit = $50

Inventory carrying cost per month per unit = $10 (based on ending month inventory)

Hiring cost per worker = $300

Firing cost per worker = $200

Beginning number of workers = 16

Each worker can produce = 50 units per month.

Month	Demand	Regular production	Overtime	Ending inventory	Workers required	Hire	Fire
1	1000
2	1200
3	1500
4	1400
Total	5,100

What is the total cost of hiring and firing the workers in a chase plan which uses only hiring and firing?
