• 14.4 bags
• 7.2 bags
• 20 bags
• 3.6 bags

Explanation:

Step1: Find flour for 12 dozen

1 dozen needs 2 cups flour, so 12 dozen needs \( 12 \times 2 = 24 \) cups flour.

Step2: Find butter sticks for 24 cups flour

4 cups flour need 2 sticks butter, so butter sticks \( = \frac{24}{4} \times 2 = 12 \) sticks.

Step3: Find chocolate chips (tablespoons)

1 stick butter needs 6 tbsp chips, so 12 sticks need \( 12 \times 6 = 72 \) tbsp chips.

Step4: Find bags of chocolate chips

1 bag has 10 tbsp, so bags \( = \frac{72}{10} = 7.2 \) bags.

Answer:

B. 7.2 bags
