Answer:
The correct answer is 12 ounces or 1.5 cups of batter will be left over.
Explanation:
1 quart is equivalent to 32 fluid ounces and 1 cup is equivalent to 8 fluid ounces, so:
2 quarts and 1 cup of cupcake batter are equivalent to (32 * 2) + 8 fluid ounces
2 quarts and 1 cup of cupcake batter are equivalent to 72 fluid ounces
Now, we have that one cupcake is made of 6 ounces of batter and if Isaac is making 10 cupcakes = 6 * 10 ounces of batter = 60 ounces
To find how much batter will be left over, we do this subtraction:
Total of batter - batter used for the 10 cupcakes
72 - 60 = 12 ounces
After making 10 cupcakes, Isaac will have 12 ounces of batter remaining, that are equivalent to 1.5 cups (12/8 = 1.5)
