Answer:
Lakeview Engine, Inc.
The net cost disadvantage if Lakeview decided to purchase the parts from the supplier per part is:
= $78
Explanation:
a) Data and Calculations:
Price by outside supplier per engine = $325
Current costs of manufacturing the engine:
Direct materials per unit = $145
Direct labor per unit = $85
Variable manufacturing overhead (20%) = $17
Fixed manufacturing overhead (80%) = $68
Total variable manufacturing cost per unit = $247
Incremental Analysis:
Make Buy Incremental
Production costs:
Variable manufacturing costs per unit:
Direct materials per unit $145
Direct labor per unit $85
Variable manufacturing per unit $17
Total variable manufacturing costs $247 $325 $78
b) Therefore, it costs more to Lakeview to buy the part from the outside supplier than it does when it makes it internally. Lakeview should continue making the parts.
