Question

10. Part U16 is used by Mcvean Corporation to make one of its products. A total of 13,000 units of this part are produced and used every year. The company's Accounting Department reports the following costs of producing the part at this level of activity:

Per Unit Direct materials $2.90

Direct labor $7.50

Variable manufacturing overhead $8.00

Supervisor's salary $3.40

Depreciation of special equipment $1.80

Allocated general overhead $7.00

An outside supplier has offered to make the part and sell it to the company for $29.80 each. If this offer is accepted, the supervisor's salary and all of the variable costs, including the direct labor, can be avoided. The special equipment used to make the part was purchased many years ago and has no salvage value or other use. The allocated general overhead represents fixed costs of the entire company, none of which would be avoided if the part were purchased instead of produced internally. In addition, the space used to make part U16 could be used to make more of one of the company's other products, generating an additional segment margin of $25,000 per year for that product. The annual financial advantage (disadvantage) for the company as a result of buying part U16 from the outside supplier should be: A) $25,000 B) ($79,000) C) ($35,400) D) $14,600

Answer 1

	Per unit		Total 13000 units
	Make	Buy	Make	Buy
Direct materials	2.90		37700
Direct labor	7.50		97500
Variable manufacturing overhead	8.00		104000
Supervisor's salary	3.40		44200
Contribution margin			25000
Purchase cost		29.80		387400
Total			308400	387400
Difference in favor of making = 308400-387400 = $79000
Financial (disadvantage) (79000)
Option B ($79,000) is correct
