1. You are negotiating to make a 7 -year loan of $55,000 to NBA Inc. To repay you, NBA Inc. will pay $4,500 at the end of Year 1,$12,000 at the end of Year 2 , and $9,500 at the end of Year 3, plus a fixed but currently unspecified cash flow, X, at the end of each year from Year 4 through Year 7 . NBA Inc. is essentially riskless, so you are confident the payments will be made. You regard 5% as an appropriate rate of return on a low risk but illiquid 7 -year loan. What cash flow must the investment provide at the end of each of the final 4 years, that is, what is X ? ( 20 points; Show all your work for partial credit.
