Company is an architectural firm specializing in home remodeling for private ­clients and new office buildings for corporate clients.

Farris charges customers at a billing rate equal to 129% of the client’s total job cost. A client’s total job cost is a combination of (1) professional time spent on the client ($ 65 per hour cost of employing each professional) and (2) operating overhead allocated to the client’s job. Farris allocates operating overhead to jobs based on professional hours spent on the job. Farris estimates its five professionals will incur a total of 10,000 professional hours working on client jobs during the year.

All operating costs other than professional salaries (travel reimbursements, copy costs, secretarial salaries, office lease, and so forth) can be assigned to the three activities. Total activity costs, cost drivers, and total usage of those cost drivers are estimated as follows:

Amy Leo hired Farris & Company to design her kitchen remodeling. A total of 27 professional hours were incurred on this job. In addition, Leo’s remodeling job required one of the professionals to travel back and forth to her house for a total of 124 miles. The blueprints had to be copied four times because Leo changed the plans several times. In addition, 16 hours of secretarial time were used lining up the subcontractors for the job.
