a. An investment offers the following cash flows: $309 one year from now, $673 two years from now, $647 in 3 years, $434 in 4 years, and $568 in 5 years. If the relevant interest rate is 8% per year (an APR, with interest compounded annually), how much is the investment worth in today's terms?
b. An investment offers the following cash flows: $150 today, $328 one year from now, $444 in 2 years, and $654 in 3 years. If the relevant interest rate is 8% per year (an APR, with interest compounded annually), what is the value of the investment 3 years from today (immediately after the cash flow at "year 3" occurs)?
Do not round any intermediate work. Round your final answer to 2 decimal places
