1. Find a set of no more than 10 (can be less than 10) cash flows with exactly 2 positive internal rates of return. Show the cash flows, the IRRs, and graph the NPV profile. (USE an Excel spreadsheet)

2. Consider a 15-year monthly annuity-style loan for $300,000. The fixed interest rate is 8.125% MEY. Amortize the loan and graph (1) payment, interest paid and principal paid v time, and separately (2) the loan balance over time. Make sure the graphs are at the top of a separate tab and suitable cleaned up.
