Lavender is considering whether to make or buy some of the components used in the production of deodorants. The annual cost of producing these components used by the company is as follows:

	Component A	Component B
Direct variable manufacturing costs	$300,000	$200,000
Direct fixed manufacturing costs	$100,000	$50,000
Allocated overhead	$50,000	$50,000
Quantity produced	100,000	200,000

The fixed manufacturing costs allocated to component A would be reduced by 80% if the company were to discontinue production of component A. As part of the company cost planning and cost control of operations and activities, management is now reviewing the unit product cost of the components used in the production of its deodorants.
