Chapter 4, Problem 74QAP
Summary Introduction
To determine: The rate at which Rule of 72 is exact.
Rule of 72:
The rule of 72 is a thumb rule which states that if the interest rate is divided by 72 then the number of periods that the amount takes to double can be calculated. By this rule, the interest rate which is needed to double a money in a given time period can also be calculated.

All of the following are the steps to figure out "The Rule of 72" EXCEPT
Find the interest rate.
O 72 divided by the interest rate.
O Roughly how many years it will take your money to double.
O Add 72 to the interest rate.
1. Find how long will it take for money to triple at {0.05, m = 2}
The rule of 72 provides a fast computation in finding the number of years required to double an
amount at a given interest rate, just divide the interest rate into 72. For example, if you want to know how
long it will take to double your money at 6%, divide 72 by 6 and get 9 years. The rule of 72 is accurate, as
long as the interest rate is less than 20%. If the unknown is the interest rate, run backward. Hence to double
an amount in 8 years, just divide 72 by 9 to find that it will require an interest rate of about 8%.

- Example 1. Compound interest When interest is compounded continuously, the rate of change of the amount x of the investment is proportional to the amount present. In this case, the proportionality constant is the annual interest rate r (as a decimal); that is, dx/dt = rx.

If the effective interest rate is i per period and you invest b dollars at time 0, then the value at time n is b(1 + i)”.

At time 2, the value will be $100 (1 + 0.06)² = $112.36. Similarly, the present value (value at time 0) of $100 received 2 years from now would be $100(1+0.06)-²≈ $88.99.
