Answer:
inflation rate = 17.5 percent per year ⇒ it will take 4 years to double
inflation rate = 35 percent per year ⇒ it will take 2 years to double
inflation rate = 3.5 percent per year ⇒ it will take 20 years to double
Step-by-step explanation:
we can use the rule of 70 to determine the amount of time it would take the general price level to double.
the rule of 70 is a simple way we can use to estimate the number of years it will take an investment to double given a certain growth rate.
70 / 17.5 = 4 years
70 / 35 = 2 years
70 / 3.5 = 20 years
