LaSalle Manufacturing had always made its components in-house. However, Jasper Component Works had recently offered to supply one component, C-430, at a price of $12 each. LaSalle uses 4,600 units of Component C-430 each year. The cost per unit of this component is as follows:

Direct materials	$7.73
Direct labor	2.32
Variable overhead	1.91
Fixed overhead	4.00
Total	$15.96

The fixed overhead is an allocated expense; none of it would be eliminated if production of Component C-430 stopped.

Required:

1. List the relevant costs for each alternative. If required, round your answers to two decimal places.
