Xerox is evaluating machinery in their manufacturing plant. One of the machines requires maintenace of $40,000 in year one, $50,000 in year two, $55,000 in year three, and $73,000 in year four. The machine will last four years and does not have a salvage value. If they chose to to replace the current machine with a new one, it would cost $350,000 now and will last 10 years with no maintenance costs. What should Xerox do? Assume their discount rate is 17%. a. Replace in Year 2, when the cumulative maintenance cost exceeds the EAC of the new machine b. Ritplace in Year 3, when the cumulative maintenance cost exceeds the EAC of the new machine c. Replace in year 4, when the maintenance cost exceeds the EAC of the new machine d. Replace in year 5, since the EAC of the new machine is higher than the maintenance cost in each year
