When the rule of 70 applies to population, dividing 70 by the percentage of population growth should equal the time (in years) that the population needs to be double (option A)

Explanation:

The rule of 70 is useful to calculate the time in which a variable of any type can be duplicated. The calculation is done by dividing the number 70 by the percentage of growth of the variable.

If, for example, the growth rate of a population is 3 percent:

70 / 3 = 23,33

This indicates that a population, with a growth rate of 3% would need about 23,33 years to double.
