Sophia‘s favorite homemade cookie recipe requires one cup of chocolate chips for 10 servings if the number of cups required for
weqwewe [10]

Answer:

3 cups

Step-by-step explanation:

We can use a proportion to find how many cups of chocolate chips she needs for 30 servings. Assuming c = cups of chocolate chips and b = batches

\frac{c}{b}

\frac{1}{10} = \frac{c}{30}

We can now multiply the diagonal values that don't include the missing variable (30 and 1) and then divide it by the value that is diagonal to the variable (10)

30 \cdot 1 = 30\\30 \div 10 = 3

Therefore, she needs 3 cups of chocolate chips to make 30 servings.
