Mountain Air Limited manufactures a line of room air purifiers. Management is currently evaluating the possible production of an air purifier for automobiles. Based on an annual volume of 10,000 units, the predicted cost per unit of an auto air purifier follows.
Direct materials $ 9.00 Direct labor 1.40 Factory overhead 10.00 Total $ 20.40
These cost predictions include $80,000 in fixed factory overhead averaged over 10,000 units.
The completed air purifier units include a battery-operated electric motor, which Mountain Air assembles with parts purchased from an outside vendor for $2.00 per motor. Mini Motor Company has offered to supply an assembled battery-operated motor at a cost of $5.50 per unit, with a minimum annual order of 5,000 units. If Mountain Air accepts this offer, it will be able to reduce the variable labor and variable overhead costs of the auto air purifier by 50 percent.
(a) Determine whether Mountain Air should continue to make the electric motor or outsource it from Mini Motor Company.
Calculate the net advantage (disadvantage) of outsourcing the electric motors from Mini Motor Company.
Use a negative sign with your answer to indicate a net disadvantage (if applicable.)

(b) If it could otherwise rent the motor-assembly space for $25,000 per year, should it make or outsource this component?
Calculate the net advantage (disadvantage) of outsourcing the motors, assuming the space could be rented.
Use a negative sign with your answer to indicate a net disadvantage (if applicable).
$Answer
(c) What additional factors should it consider in deciding whether to make or outsource the electric motors?
The quality of their own and the supplier's motors.
The dependability of the supplier.
Whether Mini Motor has a track record of meeting its commitments.
Whether they can depend on Mini Motor to supply motors for a number of years or whether it is attempting to use some temporarily idle capacity.
All of these.

Bluebird Mfg. has received a special one-time order for 15,000 bird feeders at $3 per unit. Bluebird currently produces and sells 75,000 units at $7.00 each. This level represents 80% of its capacity. These bird feeders would be marketed under the wholesalerâs name and would not affect Bluebirdâs sales through its normal channels. Production costs for these units are $3.50 per unit, which includes $2.25 variable cost and $1.25 fixed cost. If Bluebird accepts this additional business, the incremental revenue will be:

A company has the choice of either selling 600 defective units as scrap or rebuilding them. The company could sell the defective units as they are for $2.00 per unit. Alternatively, it could rebuild them with incremental costs of $0.60 per unit for materials, $1.00 per unit for labor, and $0.80 per unit for overhead, and then sell the rebuilt units for $5.00 each. What should the company do?
Multiple Choice
Since both alternatives produce a loss, store the units in hopes of a better price later.
Rebuild the units.
It does not matter because both alternatives have the same result.
Sell the units as scrap.

Granfield Company has a piece of manufacturing equipment with a book value of $40,000 and a remaining useful life of four years. At the end of the four years the equipment will have a zero salvage value. The market value of the equipment is currently $22,000.

Derby Inc. manufactures a product which contains a small part. The company has always purchased this motor from a supplier for $125 each. Derby recently upgraded its own manufacturing capabilities and now has enough excess capacity (including trained workers) to begin manufacturing the motor instead of buying it. The company prepared the following per unit cost projections of making the motor, assuming that overhead is allocated to the part at the normal predetermined overhead rate of 150% of direct labor cost.
| Direct material | $ | 38 | |
| Direct labor | 50 | ||
| Overhead (fixed and variable) | 75 | ||
| Total | $ | 163 | |
The required volume of output to produce the motors will not require any incremental fixed overhead. Incremental variable overhead cost is $21 per motor. What is the effect on income if Derby decides to make the motors?
Multiple Choice
Income will decrease by $23 per unit.
Income will decrease by $16 per unit.
Income will increase by $16 per unit.
Income will increase by $23 per unit.
