The unit costs are: Regular output =$20 Overtime =$30 

The unit costs are: Regular output = $20 Overtime = $30 Subcontract = $25 Inventory per month = $10 Backorder per month = $18 a. Given the following forecasts and steady regular output of 550 every month, what total cost would result if overtime is limited to a maximum of 40 units a month, and subcontracting is limited to a maximum of 10 units a month? (Negative answers should be indicated by a minus sign. Do not leave any empty spaces; input a O wherever it is required.)
