Answer:

  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
