International Aerospace is in the business of refurbishing corporate jets. Some parts for older planes are hard to find and they often have to cast the parts themselves using a complicated aluminum casting machine. Technology has developed to the point where they believe that they can replace this machine with a $3$D printer. The new machine shouldn't change revenue, but it will save a tremendous amount of time and energy, reducing the firm's expenses by $$75,000$ per year. Two years ago, the company spent $$25,000$ training its employees how to use $3$D printers, but ended up not purchasing any at that time.

The old machine has $5$ years of life left and is being depreciated at $$20,000$ per year for the next five years, at which time it will have a salvage value of zero. It could currently be sold for $$120,000.$ The new machine has a cost of $$250,000$ and will have a useful life of five years. The new machine will be depreciated straight line to zero over its $5-$year life. At the end of this time, it will actually have an estimated salvage value of $$50,000.$ The firm's tax rate is $35\%$ and the required rate of return is $13\%.$ What is the NPV$?$
