Johnson Enterprises uses a computer to handle its sales invoices. Lately, business has been so good that it takes an extra 3 hours per night, plus every third Saturday, to keep up with the volume of sales invoices. Management is considering updating its computer with a faster model that would eliminate all of the overtime processing. Current Machine New Machine
Original purchase cost $14,900 $25,200
Accumulated depreciation $6,600 _
Estimated annual operating costs $24,600 $19,600
Remaining useful life 5 years 5 years
If sold now, the current machine would have a salvage value of $10,200. If operated for the remainder of its useful life, the current machine would have zero salvage value. The new machine is expected to have zero salvage value after 5 years. Prepare an incremental analysis to determine whether the current machine should be replaced.

The old computer should be replaced since the differential amount of the replacing it with a new computer is $10,000
