Question

Bond A has a 7% annual coupon, matures in 12 years, and has a $1,000 face value.
Bond B has a 9% annual coupon, matures in 12 years, and has a $1,000 face value.
Bond C has an 11% annual coupon, matures in 12 years, and has a $1,000 face value.
Each bond has a yield to maturity of 9%.

If the yield to maturity for each bond remains at 9%, what will be the price of each bond 1 year from now? What is the expected capital gains yield for each bond? What is the expected total return for each bond?
I need help solving and understanding. Thank you so much!
