Pandora Media plans to issue original issue discount (OID) bonds with a 20-year maturity, $1,000 par value, and initial yield to maturity of 8%. Since these bonds are issued below par, the total yield will come from both annual coupon payments and appreciation. If the bonds are offered at a discounted price of $800, what is their nominal coupon rate? That is, at this price, what coupon rate will result in a yield to maturity of 8%? Your answer should be between 5.12 and 8.74, rounded to 2 decimal places, with no special characters
