Elite Lawn & Plowing (EL&P) is a lawn and snow plowing service with both residential and commercial clients. The owner believes that the commercial sector has more growth opportunities and is considering dropping the residential service. Twenty employees worked a total of 42,000 hours last year, 26,000 on residential jobs and 16,000 on commercial jobs. Wages were $16 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. Because of increased competition for commercial accounts, EL&P can charge $36 per hour for residential work, but only $27 per hour for commercial work. Required: a.
