I need help answering this question.

Blue Crab, Inc. plans to issue new bonds, but is uncertain how the market would set the yield to maturity. The bonds would be 19-year to maturity, carry a 13.29 percent annual coupon, and have a $1,000 par value. Blue Crab, Inc. has determined that these bonds would sell for $926.50 each. What is the yield to maturity for these bonds? Please assist.
