Question

with a population growth rate of 5% how long will it take for a population to double from 20,000 to 40,000 people?

Answer 1

20 years for the population to double from 20,000 to 40,000

Answer 2

15 years

Step-by-step explanation:

Compound growth

Equation:

20000 x 1.05 to the power of how ever many years needed

20000 x 1.05 to the power of 15 takes it just over, with 41578 people alongside decimals.

Therefore, it is 15 years.
