based on the rule of 72 how long will it take to double your money if you earn 7.2% interest
To determine how long it will take to double your money, you can use the Rule of 72. The Rule of 72 states that you can estimate the number of years it will take to double your money by dividing 72 by the annual interest rate.
In this case, the annual interest rate is 7.2%. So to find out how long it will take to double your money, you can divide 72 by 7.2:
72 / 7.2 = 10
Therefore, it will take approximately 10 years to double your money with a 7.2% annual interest rate.
