Heidt Cleaning Services (HCS) is a local custodial service company serving both the residential and commercial markets. The owner is considering dropping the commercial clients because that business seems only marginally profitable. Twenty-five employees worked a total of 37.500 hours last year, 25,000 on commercial jobs and 12,500 on residential jobs. Wages were $20 per hour for all work done. Any materials used are included in overhead as supplies. All overhead is allocated on the basis of labor-hours worked, which is also the basis for customer charges. Given current economic conditions and competition, HCS bills residential clients $40 per hour and commercial clients $30 per hour. Required: a.
