Step-by-step explanation:

When you have a wording that matches ...

  A depends on B

It means that A is the dependent variable, and B is the independent variable.

Here, the total monthly cost depends on the number of cups purchased.

That statement tells you that "total monthly cost" is the dependent variable, and "number of cups purchased" is the independent variable (x).

The first four (4) blanks you're to fill represent two different ways of saying this same thing.

__

The equation is a mathematical expression of the way the costs add up.

  total monthly cost = (program cost) + (per-cup cost) × (number of cups)

  M(x) = 15 + 2x

Then M(13) is ...

  M(13) = 15 + 2·13 = 15 +26 = 41

So the total monthly cost for the purchase of 13 cups of coffee is $41.
