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