Marsha Design is an interior design and consulting firm. The firm uses a job order cost system in which each client represents an individual job. Marsha Design traces direct labor and travel costs to each job (client). It assigns indirect costs to clients at a predetermined overhead rate based on direct labor hours.

At the beginning of the year, the managing partner, Marsha Cain, prepared the following budget:

Direct labor hours (professional)	4,300
Direct labor costs (professional)	$ 430,000
Indirect costs:
Support staff salaries	$ 37,900
Office rent	48,000
Office supplies	13,000
Total expected indirect costs	$ 98,900

Later that same year, in March, Marsha Design served several clients. Records for two clients appear below:

	Oliverio		McComb
Direct labor cost (professional)	$ 3,300		$ 2,300
Travel costs	700		300
Direct labor hours	33	hours	23	hours

Required:

1. Compute Marsha Designs predetermined overhead rate for the current year.
2. Compute the total cost of serving the clients listed.
3. Assume that Marsha charges clients $320 per hour for interior design services. How much gross profit would she earn on each of the clients above, ignoring any difference between actual and applied overhead?
