Job costing for services The Hillman Company sells and services lawn

mowers, snow blowers, and other equipment. The service department uses

a job order cost system to determine the cost of each job, such as oil changes,

tune-ups, and repairs. The department assigns conversion costs through a

cost driver rate on the basis of direct labor hours. The cost driver rate

additionally includes a markup of 25% on the job's conversion costs in order

to provide a reasonable profit for Hillman. The customer's invoice itemizes

prices for parts and labor, where the stated labor rate is the department's

cost driver rate, which includes direct labor costs, assigned overhead costs,

and the 25% markup on conversion costs. Hillman Company's service

department estimated the following information for the current year:

Salaries of mechanics $120,000
