Therefore, it would take approximately 28 years for the population to double with a growth rate of 2.5 percent.

It will take approximately 23 years for a population to double with a growth rate of 3 percent per year. This can be calculated using the rule of 70, where you divide 70 by the growth rate to find the doubling time. In this case, 70 divided by 3 equals 23.33, which can be rounded to 23 years.
