Answer:
Number of Years to Double= 10.62 years
Step-by-step explanation:
<u>First, we need to calculate the real annual interest rate:</u>
Real annual interest rate= {[(i/12)+1]^12} - 1
Real annual interest rate= [{(0.064/12) + 1]^12 - 1}
Real annual interest rate= 0.0659
<u>Now, we need to use the rule of 72. The rule of 72 is a means of estimating the number of years it takes for an investment or your money to double. </u>
<u></u>
Number of Years to Double= 70/Annual Rate of Return
Number of Years to Double= 70/6.59
Number of Years to Double= 10.62 years
