According to the Rule of 72, how can you estimate the number of years required to double an investment at a given annual interest rate?

What is the present value of \$6 to be received in 3 years, discounted at an annual interest rate of 5% compounded annually?

What is the present value of receiving \$500 at the end of each year for 10 years, assuming a discount rate of 5% per year?

What is the future value (FV) of an ordinary annuity where \$500 is invested at the end of each year for 20 years at an annual interest rate of 10%? (Use the formula: \(FV = PMT \(\times\) \(\frac{(1 + r)^n - 1}{r}\)\), where \(PMT = 500\), \(r = 0.10\), \(n = 20\).)

What is the present value of \$500 to be received in 15 years if the annual interest rate is 4.5\% compounded annually?

What is the present value (PV) of an annuity due with 5 payments of \$2 each, assuming a discount rate of 10% per period?

What is the future value of \$10 invested for 3 years at an annual interest rate of 5\% compounded annually?

What is the present value of an ordinary annuity of \$400 invested each year for 12 years at an annual interest rate of 6%? (Round your answer to the nearest dollar.)

Which interest rate is the most critical for making investment decisions when evaluating the present value of future cash flows?
