Short Exercises
S19-1 Computing single plantwide overhead allocation rates
Learning Objective 1
The Oakman Company manufactures products in two departments: Mixing and Packaging. The
company allocates manufacturing overhead using a single plantwide rate with direct labor hours as the
allocation base. Estimated overhead costs for the year are $920,000, and estimated direct labor hours are
400,000. In October, the company incurred 55,000 direct labor hours.
Requirements
1. Compute the predetermined overhead allocation rate. Round to two decimal places.
2. Determine the amount of overhead allocated in October.

S19-2 Computing departmental overhead allocation rates
Learning Objective 1
The Oakman Company (see Short Exercise S19-1) has refined its allocation system by separating
manufacturing overhead costs into two cost pools—one for each department. The estimated costs for the
Mixing Department, $620,000, will be allocated based on direct labor hours, and the estimated direct
labor hours for the year are 200,000. The estimated costs for the Packaging Department, $300,000, will
be allocated based on machine hours, and the estimated machine hours for the year are 60,000. In
October, the company incurred 16,000 direct labor hours in the Mixing Department and 15,000 machine
hours in the Packaging Department.
Requirements
1. Compute the predetermined overhead allocation rates. Round to two decimal places.
2. Determine the total amount of overhead allocated in October.

S19-4 Calculating costs using traditional and activity-based systems
Learning Objectives 1, 2
Billy and David are college friends planning a skiing trip to Killington before the new year. They
estimated the following for the trip:
Requirements
1. Billy suggests that the costs be shared equally. Calculate the amount each person would pay.
2. David does not like the idea because he plans to stay in the room rather than ski. David suggests that
each type of cost be allocated to each person based on the above-listed allocation bases. Using the
activity allocation for each person, calculate the amount that each person would pay based on his
own consumption of the activity.
