Structuring a Make-or-Buy Problem

Fresh Foods, a large restaurant chain, needs to determine if it would be cheaper to produce 5,000 units of its main food ingredient for use in its restaurants or to purchase them from an outside supplier for $12 each. Cost information on internal production includes the following:

	Total Cost		Unit Cost
Direct materials	$25,000		$ 5.00
Direct labor	15,000		3.00
Variable manufacturing overhead	7,500		1.50
Variable marketing overhead	10,000		2.00
Fixed plant overhead	30,000		6.00
Total	$87,500		$17.50

Fixed overhead will continue whether the ingredient is produced internally or externally. No additional costs of purchasing will be incurred beyond the purchase price.
