You are considering the purchase of an investment that would pay you $3889= per year for Years 1-5, $3000 per year for Years 6-8, and $2000 per year for years 9 and 10. If you require an 8.5 percent rate of return, and the cash flows occur at the end of each year, then what is the most you would be willing to pay for this investment (i.e. what is the PV of the CF stream)
