    How many 0.70 will go into 8.40?

    8.40/0.70 = 12

    12 x 3 = 36

    36 = 3 dozen

    3 cb's on sale for 0.70 = 12 cb's on sale for 4(0.70), ie.,;

    1 doz cb's on sale for 2.80.;

    n doz cb's on sale for (2.80)n.;

    n doz cb's on sale for 8.40---> (2.80)n = 8.40, ie., n = 3.

    8.4/.2333=36 bars

    36/12=3 dozen bars

    A dozen costs 4 x 0.70 = 2.80

    So you can get 8.4/2.8 = 3

    $8.40 (3bars/$0.70) (1dz bars/12 bars) = 3 dz bars

    just cancel units, no thinking needed...
