Aggregate Planning:

Given the following cost information and the aggregate plan below:

Quarter	Demand
1	800
2	400
3	1000
4	700

Previous production level	500	units
inventory holding cost	$24	per unit
hiring workers	$49	per unit
Laying off workers	$74	per unit
Subcontracting Cost	$155	per unit
Regular time production cost	$7575	per unit

Quarter	Demand	Regular time production	Ending inventory	Subcontract	Hiring	Layingoff
0		500	0
1	800	600	0	200	100	0
2	400	600	200	0	0	0
3	1000	600	0	200	0	0
4	700	600	0	100	0	0

Calculate the overall cost for quarters 1 to 4. Do not consider the production cost from quarter 0 and the cost of the inventory from quarter 0. (PLEASE SHOW CALCULATIONS)

THIS IS ALL THE QUESTION PROVIDES!!!!
