Suppose we are thinking about replacing an old computer with a new one. The old one cost us $$1,260,000$the new one will cost $$1,520,000$The new machine will be depreciated straight$-$line to zero over its five$-$year life. It will probably be worth about $ $260,000$ after five years $.$ The old computer is being depreciated at a rate of $$252,000$ per year $.$ It will be completely written off in three years. If we don't replace it now, we will have to replace it in two yearsWe can sell it now for $$380,000$ ; in two years, it will probably be worth $ $116,000.$ The new machine will save us $ $286,000$ per year in operating costs $.$ The tax rate is $24$ percent $,$ and the discount rate is $10$ percent Calculate the EAC for the old computer and the new computer $($A negative answer should be indicated by a minus sign $.$ Do not round intermediate calculations and round your answers to $2$ decimal places $,$ e$.$g$.,32\mathrm{.}16.)$ b$.$ What is the NPV of the decision to replace the computer now? $($A negative answer should be indicated by a minus sign $.$ Do not round intermediate calculations and round your answer to $2$ decimal places $,$ e$.$g$.,32\mathrm{.}16.)$
