Suppose a population of 50 crickets doubles in size every 4 months. How many crickets will there be after 5 years?

36000 crickets.

Step-by-step explanation:

1 year is 12 months, so 12/4=3.

First you would multiply 50 and 4, which is 200. Then you would multiply 200 and 3, which is 600.

5x12 years is 60, so you would have to multiply 600 and 60, which is 36000
