Question

A certain population of rabbits is doubling its population every 2 months. The original population started with only 20 rabbits. A biologist studying the population found that the equation 1000=20(2)t shows how many months, t, it will take before there are 1000 rabbits in the population.

Answer 1

on solving the given equation , your answer is attained .

$1000 = 20(2)t \\ 1000 = 40(t) \\ 1000 \div 40 = t \\ 100 \div 4 = t \\ t = 25$

therefore it takes 25 months to get a population of 1000 rabbits
