A 5-year annuity of ten $4500 semiannual payments will begin 9 years from now, with the first payment coming 9.5 years from now. If the discount rate is 12% compounded monthly, what is the value of this annuity five years from now? What is the value three years from now? What is the current value of the annuity?

I have calculate the PVa at t=9 is 73073.68, but I don't know how to do the next steps...

Please explain as clearly as possible

Thanks!!
