$3.$ A project costs $$20,000,$ will be depreciated straight$-$line to zero over its $3$ year life, and will require a net working capital investment of $$5,000$ up$-$front. The project generates OCF of $$13,000.$ The fixed assets will be sold for $$2,000$ at the end of the project. If the firm has a tax rate of $34\%$ and a required return of $10\%,$ what is the project NPV$?$
