Answer: 4%
Explanation:
The Rule of 72 allows us to calculate the number of years it would take for an investment to double.
It works by dividing 72 by the rate to find the number of years.
Number of years = 72/ rate
As we are looking for the rate, the formula becomes:
Number of years = 72/ rate
Rate * Number of years = 72
Rate = 72 / Number of years.
Rate = 72 / 18
= 4%
