Note: The predetermined manufacturing overhead rates shown below are from the solutions to S3-5.
Req. 1
Total manufacturing
overhead allocated
=
Actual use of cost allocation base × Predetermined manufacturing overhead
rate
=
62,550 hours × $25 per direct labor hour
=
$1,563,750
Req. 2
Total manufacturing
overhead allocated
=
Actual use of cost allocation base × Predetermined manufacturing overhead
rate
=
$1,245,000 × 125%
=
$1,556,250
Req. 3
Total manufacturing
overhead allocated
=
Actual use of cost allocation base × Predetermined manufacturing overhead
rate
=
38,000 machine hours × $40 per machine hour
=
$1,520,000
Req. 4
The total amount of manufacturing overhead allocated during the year is dependent upon two factors: the allocation
base used and the actual manufacturing overhead for the year.
As a result, a company could either overallocate or underallocate manufacturing overhead, depending on the
allocation base used and the actual manufacturing overhead for the year.
Note: Student answers may vary.

Manufacturing overhead is underallocated by $30,000.
Req. 4
In this company’s particular case, using direct labor hours as an allocation base resulted in overcosting the jobs by
$13,750. Using direct labor cost as an allocation was the best option, causing jobs to be slightly overcosted by $6,250
during the year. Using machine hours led to the least accurate allocation: Jobs were undercosted by a total of $30,000.

Req. 3
Whether or not Rosa wins the bid will depend on the allocation base the company chose to use during the year. Rosa’s
bid price will be $142,266 if the company uses direct labor hours as the allocation base. In this case, the company will
probably lose the job to Mauzy Recycling, since their bid was only $125,000. However, Rosa will probably win the bid if
machine hours are used as the allocation base. Using machine hours as an allocation base results in a bid price of
$111,743.
