Hello can you please provide assistance with the below questions? I got 16.86 for question 2 and it is wrong and 7.023 for question 1, which is also wrong.

1. The market price is $700 for a 9-year bond ($1,000 parvalue) that pays 11 percent annualinterest, but makes interest payments on a semiannual basis (5.5 percentsemiannually). What is thebond's yield tomaturity?
2. AbnerCorporation's bonds mature in 16 years and pay 8 percent interest annually. If you purchase the bonds for $1,100, what is your yield tomaturity?
