What is a Function?

A function is a law that relates an independent and a dependent variable.

If l represents the number of laps she walks

and d represents the number of dollars she raises

She raises $5 for each lap she walks, so it is dependent upon how much she walks to determine the amount she raised.

Therefore, the independent variable = number of laps; dependent variable = number of dollars. The correct option is D.
