    There's a flat $19 fee:

    C = 19 + ...

    And then there is an amount based on the power consumed (0.09 for each P consumed).

    C = 19 + 0.09P

    The commutative property says we can add in either order, so swap it around:

    C = 0.09P + 19

    Which one does that match with?

    Answer:

    A) C = 0.09P + 19
