Answer
Explanation:
Step1: Use the rule - of - 72
The rule of 72 is a quick way to estimate the number of years it takes for an investment to double. The formula is $t=\frac{72}{r}$, where $t$ is the time in years and $r$ is the interest rate.
Step2: Substitute the interest rate
Given $r = 1%$, substituting into the formula $t=\frac{72}{1}$. $t = 72$
Answer:
72 Years
