Jason Rogers works full-time for UPS and runs a lawn-mowing service part-time after work during the warm months of April through October. Jason has two men working with him, each of whom is paid $6.00 per lawn mowing. Jason has 31 residential customers who contract with him for once-weekly lawn mowing during the months of May through September, and twice-per-month mowings during April and October. On average, Jason charges $46 per lawn mowed. Recently, LStar Property Management Services asked Jason to mow the lawn at each of its 25 rental houses every two weeks during the months of May through September. LStar has offered to pay $25 per lawn mowing, and would forego the lawn edging that normally takes Jasons team about half of its regular mowing time. If Jason accepts the job, he can assign a one-man team to mow the rental house yards, and will have to buy an additional power lawn mower for about $360 used. Fuel to run the additional mower will be about $0.50 per yard.
