There are 4 alligators living on a golf course in Florida. If the number of alligators doubles every six months, how many alligators will there be at the end of a year? Let's think first. Chain of thought:
First figure out how many times the alligator population doubles in one year by dividing the number of months in a year by the number of months it takes the population to double: 12 months / 6 months = 2. The alligator population doubles twice. Now double the alligator population once: 4 alligators * 2 = 8 alligators. Now double it again: 8 alligators * 2 = 16 alligators.
Therefore, the answer is 16.
