Ira Lisetskai [31]

Answer:

There are 16 servings

Step-by-step explanation:

<u>First, find how many oz are in 5 quarts. </u>

<em>Think: In one quart there are 32 ounces, in 5 quarts how many ounces would that be?</em>

5 x 32 = 160 ounces

<u>Next, divide 160 ounces by 10 servings</u>

160 / 10 = 16 servings

So there are 16 servings in a 5 quart pitcher.

Hope this helps ;)
