Edinaman Company $($Edinaman$)$ currently processes seafood with a unit purchased several years go$.$ The unit, which originally cost $$500,000,$ currently has a book value of $$250,000.$ Edinaman is considering replacing the existing unit with a newer, more efficient one. The new unit will cost $$700,000$ and will require an additional $$50,000$ for delivery and installation and require Edinaman to increase initial net working capital $($NWC$)$ by $$40,000.$ The new unit will be depreciated on a straight$-$line basis over $5$ years to zero balance. Edinaman expects to sell the existing unit for $$275,000.$ Edinamans marginal tax rate is $40\%.$ If Edinaman purchases the new unit, its annual revenues are expected to increase by $$100,000($due to increased processing capacity$)$ and its annual operating costs are expected to decrease by $$20,000.$ Annual revenues and operating costs are expected to remain constant at this new level over the $5-$year life of the project. After $5$ years, the new unit will be completely depreciated and expected to be sold for $$70,$
