A 30-year annuity will pay $10,000 per year, beginning a year from today (i.e., t=1). If the interest rate is 6% per year, compounded annually, for the first 15 years and 8% per year, compounded annually, for the subsequent 15 years, what is the present value of the annuity at t=0? What is the future value of the annuity at t=30?
