D.

Answer 1

To calculate the amount of each ingredient Helen uses for 12 sandwiches, we can multiply the required amount for one sandwich by 12.

1. Bread:

   • Each sandwich requires 2 slices of bread.
   • For 12 sandwiches: \( 2 \text{ slices} \times 12 = 24 \text{ slices} \)

2. Turkey:

   • Each sandwich requires \( \frac{1}{8} \) pound of turkey.
   • For 12 sandwiches: \( \frac{1}{8} \text{ pound} \times 12 = \frac{12}{8} = \frac{3}{2} = 1.5 \text{ pounds} \)

3. Cheese:

   • Each sandwich requires \( \frac{3}{2} \) slices of cheese (which is equivalent to 1.5 slices).
   • For 12 sandwiches: \( \frac{3}{2} \text{ slices} \times 12 = \frac{36}{2} = 18 \text{ slices} \)

Putting it all together, Helen uses:

• 24 slices of bread,
• 1.5 pounds of turkey,
• and 18 slices of cheese.

So the correct answer is:

C. 24 slices of bread, 1.5 pounds of turkey, and 18 slices of cheese.
