Consider the following aggregate planning problem for one quarter:

	Regular Time	Overtime	Subcontracting
Production Capacity/Month	1,000	200	150
Production Cost/Month	5	7	8

Assume that there is no initial inventory and there is forecasted demand of 1,250 units in each month in the quarter. Carrying cost is $1 per unit per month, and backlogs are not allowed. Use the transportation model to find the optimal solution.

How much excess capacity is there? [ Select ] ["300", "1250", "100", "0"] units

What is the cost of the optimal solution? [ Select ] ["$28,600", "$26,600", "$20,400", "$22,400"]

How many units are actually made by subcontracting? [ Select ] ["150", "0", "100", "450"]

How many units incur a holding cost? In other words, how many are made in one month and held to meet the demand of a future month? [ Select ] ["1250", "0", "3750", "450"] units
