determined by interest rates

and time to maturity

by the following:

You know that the maturity is $8\mathrm{.}94$ years, but unfortunately you forgot the exact interest rate. You think it is $3\mathrm{.}44\%,$ but you are not sure. However, you feel confident that the is not off by more than $+or-0\mathrm{.}23$

What is your absolute percent error in the bond price?
