Medium-Sized Collections

In Collection #3 (Table 12-2), you have about the same number of red bricks as you had in Collection #2 (Table 12-1) but a few more red plates. In addition, you now have two additional colors to deal with as well; there are both blue and white plates in this collection. The quantity of red plates still dictates that they have their own pile. The bricks, since they are different types of pieces, belong in their own pile as well. This leaves you with just the blue and white plates.
