A coffeepot contains 1 1⁄2 quarts of coffee. After Tonya pours an equal amount of coffee into two cups, 3 1⁄2 cups of coffee remain in the pot. How much coffee did Tonya pour into each cup?

cup and ounces

Convert the 1 1/2 quarts into cups.

4 cups = 1 quart

1 1/2 q = 3/2 q (4 c / 1 q) = 6 cups.

The amount poured out:

6 c - 3.5 c = 2.5 cups

The amount in cups:

2.5/2 = 1.25 cups

Ounces per cup:

1.25 c (8oz/1c) = 10 oz
