Optional Question #1. (can substitute for one of the prompts above): Calculate the IRR and NPV for the following capital project: The initial outlay is $700,000.00. The Net Cash Flow (after taxes and depreciation) is constant at $118,861.00 for 10 years. The salvage value is zero. The required rate of return or discount rate is 9%. Is this capital project worthy of consideration?

or
Optional Question #2: A machine costs $12,000 and is expected to operate for 10 years.  The estimated salvage value is zero.  It will save the company $2,500 per year before taxes and depreciation. The company depreciates its assets on a straight-line basis and has a marginal tax rate of 40 percent.  If the company’s cost of capital is 14%, should this machine be purchased using the IRR criterion? (Hint: This is similar to exercise 17.2 in your text book.  The solution is in Appendix D. )
