Assume the interest rate in the market $($yield to maturity$)$ goes down to $8$ percent for the $10$ percent bonds. What is the bond price on a $10-$year, a $20-$year, and a $25-$year time period $($hint: par value $$1,000$& pays $10\%$ annually$).$

$\backslash$table$[[,$Maturity,Bond Price$],[,10$ year,$($$$1,134,00)$

The question above has the "bond price" or answers already posted I just need help with step by step on how to get the answer. Thank you
