Use the XNPV function to obtain an exact answer to problem 3. 5. 15 and cash flows occur at the end of the year. 42 Chapter 8: Evaluating Investments with Net Present Value Criteria Chapter 9: Internal Rate of Return 43 6. Solve problem 5 assuming cash flows occur at the beginning of each year. 7. 15, what is the NPV of these cash flows?

Which is the better investment? Investment 1 yields total cash inflow of $0, while investment 2 yields a total cash flow of $1,000. At first glance, investment 2 appears to be better. But wait a minute. Most of the cash outflow for investment 1 occurs two years from now, while most of the cash outflow for investment 2 occurs today. 00 today, so maybe investment 1 is better than it first appears.

This formula ( MID for Middle) begins with the 13th character and then extracts the number of characters equal to the total number less the 12 characters at the beginning (the product ID) and the 6 characters at the end (price).
