An investor who owns a bond with a 9% coupon rate that pays interest semiannually and matures in three years is considering its sale. If the yield-to-maturity on the bond is 11%, find the price of the bond per 100 of par value.

I've looked at other answers to this question and still can't figure it out. For example, I know that interest is 4.5 and number of periods is 6 but I have no idea how to do the rest. Please be as detailed as possible.
