5) the management of rathburn corporation would like to investigate the possibility of
basing its predetermined overhead rate on activity at capacity rather than on the
estimated amount of activity for the year. the company’s controller has provided an
example to illustrate how this new system would work. in this example, the allocation
base is machine-hours and the estimated amount of the allocation base for the upcoming
year is 43,000 machine-hours. in addition, capacity is 47,000 machine-hours and the
actual activity for the year is 42,600 machine-hours. all of the manufacturing overhead
is fixed and is $848,820 per year. for simplicity, it is assumed that this is the estimated
manufacturing overhead for the year as well as the manufacturing overhead at capacity
and the actual amount of manufacturing overhead for the year. job f31i, which required
310 machine-hours, is one of the jobs worked on during the year.
required:
a. determine the predetermined overhead rate if the predetermined overhead rate is
based on the estimated amount of the allocation base.
b. determine how much overhead would be applied to job f31i if the predetermined
overhead rate is based on estimated amount of the allocation base.
