Lily mixed a batch of punch for the class party. Her recipe called for 2 1/2 cups of orange juice, 1 1/2 cups lemonade, and 3 quarts of ginger ale. How many 1-cup servings does the recipe make?

16 1-cups servings

Step-by-step explanation:

First, you'll need to convert the 3 quarts to cups. One quart is 4 US cups, so quarts is 12 US cups. Next, add the 2 1/2 cups of OJ and 1 1/2 cups of lemonade together, which gives you 4 US cups. Add your 12 cups and 4 cups together and you get 16. You'll get 16 1-cup servings.
