Susan Meyer, owner/manager of Meyer's Motor Court in Key West, is considering outsourcing the daily room cleanup for her motel to Duffy's Maid Service. Susan rents an average of 50 rooms for each of 365 nights (365 x50) per room plus a fixed cost of $25,000 for sundry items such as uniforms with the motel's name. Susan's annual fixed cost for space, equipment and supplies is $61,000. Which is the preferred process for Susan and why?
