2. A staples truck is delivering notebooks to CMS. There are 212 boxes with 198 notebooks in each box. How many total notebooks are there?

Answer 1

Explanation:

2) 212*198 = 41 976

1) 80-37 = 43

Answer 2

9514 1404 393

Answer:

1. SCR (or PPW). 43 more flavors

2. GLT. 41,976 notebooks

Explanation:

1. Conceptual key: SCR

Lizzy is starting with 37 flavors. She wants a result of 80 flavors, so the change can be computed from ...

37 + x = 80

x = 80 -37 = 43

Lizzy needs to create 43 more flavors.

Additional comment

This might also be considered to be using the PPW pattern, as both the number she has and the number she creates make up the whole number. The SCR key may better apply to cases where a "rate of change" is involved. There is no rate of change in this problem.

2. Conceptual key: GLT

There are 212 groups of 198 notebooks, so the total is the number of groups times the number in each group.

(212 boxes)(198 notebooks/box) = 41,976 notebooks
