    B. 3*2 - 3*0.05

    Step-by-step explanation:

    To find the price of 3 boxes of cereal, we multiply the price of one box by 3. If we're doing this mentally, we probably find it easier to consider ...

    1.95 = 2.00 - 0.05

    Then the price of 3 boxes is ...

    3 (1.95) = 3 (2.00 - 0.05) = 3*2 - 3*0.05
