The future value and present value equations also help in finding the interest rate and the number of years that correspond to present and future

value calculations.

If a security currently worth $$12,800$ will be worth $$16,843\mathrm{.}93$ seven years in the future, what is the implied interest rate the investor will earn on the

security$-$assuming that no additional deposits or withdrawals are made?

$1\mathrm{.}32\%$

$0\mathrm{.}19\%$

$7\mathrm{.}60\%$

$4\mathrm{.}00\%$

If an investment of $$40,000$ is earning an interest rate of $4\mathrm{.}00\%,$ compounded annually, then it will take

for this investment to reach

a value of $$53,679\mathrm{.}69-$assuming that no additional deposits or withdrawals are made during this time.

Which of the following statements is true$-$assuming that no additional deposits or withdrawals are made?

If you invest $$1$ today at $15\%$ annual compound interest for $82\mathrm{.}3753$ years, you'll end up with $$100,000.$

If you invest $$5$ today at $15\%$ annual compound interest for $82\mathrm{.}3753$ years, you'll end up with $$100,000.$
