1 answer

In this situation, the independent quantity is the mileage driven, as it is the variable that you can control or change. The dependent quantity is the amount of gasoline remaining in the tank, as it depends on the mileage driven.

So the correct identification is:

mileage driven; amount of gasoline remaining in the tank.
