73) Part S51 is used in one of Haberkorn Corporation’s products. The company makes 12,000 units
of this part each year. The company’s Accounting Department reports the following costs of

An outside supplier has offered to produce this part and sell it to the company for $37.70 each. If
this offer is accepted, the supervisor’s salary and all of the variable costs, including 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. If the outside supplier’s offer were accepted, only $17,000 of these allocated
general overhead costs would be avoided.
The annual financial advantage (disadvantage) for the company as a result of buying the part from
the outside supplier would be:
A) ($5,800)
B) ($22,800)
C) ($149,800)
D) ($39,800)
74) Rebelo Corporation is presently making part E07 that is used in one of its products. A total of

An outside supplier has offered to make and sell the part to the company for $20.80 each. If this
offer is accepted, the supervisor’s salary and all of the variable costs, including 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. If management decides to buy part E07 from the outside supplier rather than to continue
making the part, what would be the annual impact on the company’s overall net operating income?
A) ($6,800)
B) ($163,200)
C) $163,200
D) $6,800

An outside supplier recently began producing a comparable motor that could be used in the sewing
machine. The price offered to SP Corporation for this motor is $18. If SP Corporation decides not
to make the motors, there would be no other use for the production facilities and none of the fixed
manufacturing overhead cost could be avoided. Direct labor is a variable cost in this company. The
annual financial advantage (disadvantage) for the company as a result of making the motors rather
than buying them from the outside supplier would be:
A) $276,000

76) Part U16 is used by McVean Corporation to make one of its products. A total of 13,000 units of

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
77) Sardi Inc. is considering whether to continue to make a component or to buy it from an outside
supplier. The company uses 17,000 of the components each year. The unit product cost of the
component according to the company’s cost accounting system is given as follows:
Direct materials
$
8.20
Direct labor
8.30
Variable manufacturing overhead
1.20
Fixed manufacturing overhead
4.30
Unit product cost
$
22.00
Assume that direct labor is a variable cost. Of the fixed manufacturing overhead, 70% is avoidable
if the component were bought from the outside supplier. In addition, making the component uses 2
minutes on the machine that is the company’s current constraint. If the component were bought,
time would be freed up for use on another product that requires 4 minutes on this machine and that
has a contribution margin of $7.00 per unit.
When deciding whether to make or buy the component, what cost of making the component should
be compared to the price of buying the component?
A) $24.21 per unit
B) $25.50 per unit
C) $20.71 per unit
D) $22.00 per unit

The part can be purchased from an outside supplier at $20 per unit. If the part is purchased from the
outside supplier, two thirds of the total fixed costs incurred in producing the part can be avoided.
The annual financial advantage (disadvantage) for the company as a result of buying the part from
the outside supplier would be:
A) $3,000

An outside supplier has offered to provide the annual requirement of 4,000 of the parts for only
$14 each. The company estimates that 60% of the fixed manufacturing overhead cost above could
be eliminated if the parts are purchased from the outside supplier. Assume that direct labor is an
avoidable cost in this decision. Based on these data, thefinancial advantage (disadvantage) of
purchasing the parts from the outside supplier would be:

The City of Clearwater would like to purchase 3,000 air conditioners from CoolAir but only if they
can get them for $75 each. Variable selling and administrative costs on this special order will drop
down to $2 per unit. This special order will not affect the 60,000 regular sales and it will not affect
the total fixed costs. The annual financial advantage (disadvantage) for the company as a result of
accepting this special order from the City of Clearwater should be:
A) ($21,000)

81) A customer has requested that Lewelling Corporation fill a special order for 9,000 units of
product S47 for $20.50 a unit. While the product would be modified slightly for the special order,
product S47’s normal unit product cost is $14.40:

Assume that direct labor is a variable cost. The special order would have no effect on the
company’s total fixed manufacturing overhead costs. The customer would like modifications made
to product S47 that would increase the variable costs by $5.00 per unit and that would require an
investment of $36,000 in special molds that would have no salvage value. This special order would
have no effect on the company’s other sales. The company has ample spare capacity for producing
the special order. The annual financial advantage (disadvantage) for the company as a result of
accepting this special order should be:
