7 cups

Answer 1

To determine how many cups of flour are needed to make 10 servings, we can start by finding the amount of flour needed for one serving.

The original recipe calls for 3.5 cups of flour for 7 servings. So, the amount of flour per serving is:

\[
\frac{3.5 \text{ cups}}{7 \text{ servings}} = 0.5 \text{ cups per serving}
\]

Now, to find out how much flour is needed for 10 servings, we multiply the amount of flour per serving by the number of servings:

\[
0.5 \text{ cups/serving} \times 10 \text{ servings} = 5 \text{ cups}
\]

Therefore, you need **5 cups** of flour to make 10 servings.

The correct answer is **5 cups**.
