Grouper, a large manufacturing company, currently uses a large printing press in its operations and is considering two replacements: the PDX341 and PDW581. The PDX costs $484,000 and has annual maintenance costs of $8,400 for the first 5 years and $13,400 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 $121,000 and requires maintenance of $26.800 a vear for its 10-vear life. The salvage value of the PDW is expected to be zero in 10 vears. Assuming that Grouper must replace its current printing press (it has stopped functioning), has a(n) 10-percent cost of capital, and all cash flows are after tax, which replacement press is the most appropriate? Calculate the NPV using the chain replication approach.

Provide me with the formulas and what to insert in the calculator (No Excel)
