Jupiter, a large candy company, is having great success with its "Swan" family of candy bars. Due to a number of factors they like to plan their production at least nine months into the future. The table below contains their demand projections (in tons) for April through December:

Overtime cost/ton	$66
Subcontracting cost/ton	$75

Here is some additional relevant (capacity) information:

Regular production tons/employee/month	25
Max regular production/tons/month	3,000
Max overtime production/tons/month	1,500
Max subcontractor production/tons/month	2,000

Given the above information (and don't overlook beginning number of employees and inventory levels in the first table), create a level production plan with only the use of regular production and no inventory left over at the end of the six-month period.

What is the regular production cost (over the six months from January through June) for a level production plan?

What is the total overtime production cost for this production plan?

What is the total subcontract cost for this production plan?

What is the total holding cost for this production plan?

What is the total hire cost for this production plan?

What is the total fire cost for this production plan?

What is the total cost (sum of all costs) for this production plan?
