3. The Rule of 72 is a very useful approximation for understanding exponential growth. The Rule states that (72 / the interest rate) = doubling time. For example, if the interest rate is 10% and you invest $10 today, in 7.2 years you will have $20. (72/10 = 7.2, the doubling time) My sister, a financial planner, would suggest that you save today for peace of mind. So today, let's put $1,000 in a mutual fund that rather consistently yields...

4. Imagine the human population of the Earth as an investment that is deposited on the planet with a growth rate-"investment return" of 2% per year, con- tinuously compounded. (The actual current figure is a little lower; if you are curious, look up the latest figure and modify this problem accordingly.) Think of the current population, 7 billion people, as the present value of an invest- ment. Imagine "paying out" a stream of human population, by putting people on spaceships...
