There are 4 cups in 1 quart.

solution

You need to find how many glasses Mrs. Austin can fill with milk. But first, you need to know how much milk she has.

She has 3 quarts of whole milk. She also has 1 quart of soy milk.

Mrs. Austin has 4 quarts of milk, but each glass has 1 cup of milk. So, find how many cups are in 4 quarts. There are 4 cups in a quart, so multiply by 4.

Mrs. Austin has 16 cups of milk. Since each glass has 1 cup of milk, she can fill 16

glasses.
