    the answer for the question is......
    let x be the cost of the 56 copies
    word ratio, ratio table, find x

    cost copies
    0.66 12
    x 56

    12(x) = 0.66(56)
    12 x = 36.56/12
    x = $3.08

    56 copies cost $3.08

    The answer for your question is:
    ~56 copies would cost $3.08
    (I got the answer by doing cross multiplication)
