Answer:
Buy
Step-by-step explanation:
Allocated fixed costs are irrelevant for this decision because they can not be avoided, regardless of the alternatives being considered.
Making
Variable Cost ($1.95×40,000 units) $78,000
Fixed Costs $65,000
Total $143,000
Buying
Price ($3.50×40,000 units) $140,000
It costs $3,000 more to make the component than to buy from outside supplier.
Therefore, buy this component from the outside supplier
