Explanation:

Step1: Define Independent Variable

The independent variable is the one that is manipulated or chosen freely. Here, the number of text messages sent is chosen by the user, so it's independent.
Independent variable: the number of text messages sent

Step2: Define Dependent Variable

The dependent variable depends on the independent variable. The monthly bill (cost) depends on how many text messages are sent, so it's dependent.
Dependent variable: the monthly cost of the cell phone

Step3: Describe the Function

A function describes how the dependent variable depends on the independent variable. So the monthly cost is a function of the number of text messages sent.

Independent variable: the number of text messages sent
Dependent variable: the monthly cost of the cell phone
