Your firm is considering replacing a manual welding process with a robotic welding platform. The robotic welding platform will cost $$3,200,000$ and will be depreciated straight$-$line to a book value of $$0$ over its $10-$year life. The annual cost savings from switching to this platform is expected to be $$475,000$ per year. Due to its higher efficiency, net working capital $($NWC$)$ can be reduced by $$200,000$ upon purchase $)=(0$; this number will be reversed in the last year $).$ Assume no salvage value.

If your tax rate is $21\frac{\%}{?}$ year and your firm's cost of capital is $8\frac{\%}{?}$ year, what is the NPV of this investment?
