The average U.S. growth rate since 2008 has been 1.5% per year. Using the rule of 72, how long will it take for the size of the U.S. economy to quadruple at this growth rate?
Growth rate = 1.5%
As per rule of 72
# of years it takes for economy to double = 72 / growth rate = 72 / 1.5 = 48 years
# of years it will take for economy to quadruple = 48 * 2 = 96 years
It will take 96 years for the size of US economy to quadruple
