Compute the total cost for each aggregate plan using these unit costs:

Regular output = K35

Overtime = K55

Subcontract = K60

Average Balance Inventory = K10

Month	Jan	Feb	Mar	Apr	May	Jun
Forecast Output	300	320	320	340	320	320
Regular	300	300	300	300	300	300
Overtime	20	20	20	20	20	20
Subcontract	0	0	0	0	0	0

After complaints from some workers about working overtime every month during the first half of the year, the manager is now considering adding some temporary workers for the second half of the year, which would increase regular output to a steady 350 units a month, not using any overtime, and using subcontracting to make up needed output. Determine the total cost of that plan. Should the manager entertain workers complaints? Explain.
