solution

Read the problem.

A Bow-Wow chew toy costs $20. 10% of the purchase price is donated to an animal shelter. How much is donated for each chew toy?

The total cost of a chew toy, or 100% of the cost, is

$20.

So, this model represents the problem.

100

Now, find how much money is donated to an animal shelter for each chew toy. First, divide to find how much each part of the model represents. The whole model represents $20, and there are 10 equal parts.

Each part represents $2. You can count by 2s to label the bottom of the model.

100

Since 10% of the $20 cost for each chew toy is donated to an animal shelter, $2 is donated for each chew toy.
