The market yield is currently 7.9% on twenty-year semiannual bonds. If Lunar wants to issue a 6.5% semiannual coupon bond, how many bonds will it need to sell to raise the $5,600,000? Assume that all bonds are issued at a par value of $1,000. How many bonds will Lunar need to sell to raise the $5,600,000? (Round to the nearest whole number.)
