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

Regular output = $40

Overtime = $50

Subcontract = $60

Average Balance inventory = $10

a.

b.

c. 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.
