2. A population of honeybees grows at an annual rate equal to 1/4
the number present when there are no more than 10,000 bees. If
there are more than 10,000 bees but fewer than 50,000 bees, the
growth rate is equal to 1/12 of the number present. If there are
5000 bees now, when will there be 25,000 bees?
