The two variables that we should use are:

<h3>What variables should we use?</h3>

Here we want to study a relation between the cost per call as the function of the minutes that the call lasted.

So, we need to use two variables, x will be the number of minutes that call lasted, this is the independent variable.

And the variable that depends on that should be the cost of the call, let's say, y is the cost of the call.

These are the two variables that we need to model the situation:

y = f(x)

There says:

<em>"The cost of the call is a </em><em>function </em><em>of the number of minutes that the call lasted".</em>
