A project has a total up$-$front cost of $\backslash (\backslash$$ $700\backslash ).$ The cash flows are $\backslash (\backslash$$ $200\backslash )$ in the first year, $\backslash (\backslash$$ $350\backslash )$ in the second year, and $\backslash (\backslash$$ $250\backslash )$ in the third year. What's the IRR? If we require a $20$ percent return, should we take this investment?
