    6 packs, 9 packs

    Step-by-step explanation:

    The ratio of mechanical pencil to free eraser is 2:4, or 1:2.

    So that means, for every free eraser you get, you bought the double amount of pencils.

    12 free erasers x 2 = 24 pencils

    18 free erasers x 2 = 36 pencils

    And a pack of pencils contains 4.

    24/4 = 6 packs

    36/4 = 9 packs
