MedCo, a large manufacturing company, currently uses a large printing press in its operations and is considering two replacements: the PDX$341$ and PDW$581.$ The PDX costs $$400,000$ and has annual maintenance costs of $$10,000$ for the first $5$ years and $$15,000$ for the next $10$ years. After $15$ years, the PDX will be scrapped $($salvage value is zero$).$ In contrast, the PDW can be acquired for $$100,000$ and requires maintenance of $$30,000$ a year for its $10-$year life. The salvage value of the PDW is expected to be zero in $10$ years. Assuming that MedCo must replace its current printing press $($it has stopped functioning$),$ has an $8-$percent cost of capital, and all cash flows are after tax, which replacement press is the most appropriate?
