C. 7 cups
D. 4 cups

Answer 1

Ruby needs 9 cups (option B) of powdered milk and whole wheat flour combined to make 4 batches of pancakes.

Step-by-step explanation:

The student's question asks how many combined cups of powdered milk and whole wheat flour are needed if Ruby plans on making 4 batches of pancakes, given that the recipe calls for ¼ of a cup of powdered milk and 2 cups of whole wheat flour for each batch.

For powdered milk, you would multiply the quantity needed for one batch (¼ cup) by the number of batches (4):

¼ cup × 4 = 1 cup.

For whole wheat flour, you would multiply the quantity needed for one batch (2 cups) by the number of batches (4):

2 cups × 4 = 8 cups.

Then, add the total cups of powdered milk and whole wheat flour together:

1 cup + 8 cups =

9 cups. Option B is correct answer.

Therefore, Ruby needs a total of 9 cups of powdered milk and whole wheat flour to make 4 batches of pancakes.
