Answer:
Net operating income would decrease by $36,000 per year.
Step-by-step explanation:
The company's current cost of manufacturing a part Z95 is $33.9 which includes all the material, labor and overhead costs. If the company buys this part from an outside supplier it will cost $24.10 each. but the depreciation and factory overhead cannot be avoided. The depreciation is $5.40 and factory overheads are $8.60. This will be added to the cost of buying each part.
$24.10 + $5.40 + $8.60 = $38.1
The cost of buying the part is greater than the cost of making it.
