17. independent practice u1a2 Example 6
A forager honeybee spends three weeks becoming accustomed to the immediate surroundings of its hive and spends the rest of its life collecting pollen and nectar. The total number of miles T a forager honeybee flies in its lifetime L (in days) can be modeled by the equation below, where m is the number of miles it flies each day.
