Answer:
If the company makes the units in-house, it will save $10,000.
Explanation:
The fixed costs will remain in both options. Therefore, the fixed costs are irrelevant to the decision-making process.
Buy:
Total cost= 10,000*16= $160,000
Make in house:
Total cost= 10,000*(9 + 4 + 2)= $150,000
If the company makes the units in-house, it will save $10,000.
