adell [148]

Answer:

<em>4 pounds of ingredients are used in each batch.</em>

Step-by-step explanation:

Amount of flour = 21\frac{1}{2}pounds = \frac{43}{2}pounds

Amount of butter = 8 pounds

Amount of sugar = 18\frac{1}{2}pounds= \frac{37}{2} pounds

So, the <u>total amount of all ingredients</u> will be:   (\frac{43}{2}+\frac{37}{2}+8)pounds = (\frac{43+37+16}{2}) pounds= \frac{96}{2} pounds = 48 pounds

Given that, she makes 12 batches of cookies using all the ingredients.

Thus, the amount of ingredients used in each batch =\frac{48}{12} pounds = 4 pounds
