A best-selling author decides to cash in on her latest novel by selling the rights to the books royalties for the next six years to an investor. Royalty payments arrive once per year, starting one year from now. In the first year, the author expects $400,000 in royalties, followed by $300,000, then $100,000, then $10,000 in the three subsequent years. If the investor purchasing the rights to royalties requires a return of 7% per year, what should the investor pay?
