3. Symon Meats is looking at a new sausage system with an installed cost of $245,000. The cost will be depreciated straight-line to zero over the projects five-year life, at the end of which the sausage system can be scrapped for $30,000. The sausage system will save the firm $85,000 per year in pretax operating costs, and the system requires an initial investment in net working capital of $13,000. If the tax rate is 34 percent and the discount rate is 10 percent, what is the NPV of this project?

Please show step by step calculations so I can see how you obtained the answer.
