A best-selling author decides to cash in on her novel by selling the rights to the book's royalties for the next four 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 royaltie requires a return of 7 percent per year, what should the investor pay?
