Applied Nanotech is thinking about introducing a new surface cleaning machine. The marketing department has come up with the estimate that the company can sell $16$ units per year at $$298,000$ net cash flow per unit for the next four years. The engineering department has come up with the estimate that developing the machine will take a $$14\mathrm{.}2$ million initial investment. The finance department has estimated that a discount rate of $13$ percent should be used.

What is the base$-$case NPV$?($A negative answer should be indicated by a minus
