A language model was prompted with a question and produced a correct line of reasoning but did not state the final answer, as shown below. Write a single, effective follow-up prompt that incorporates both the original question and the model's reasoning to extract the final answer.

Original Question: "A recipe calls for 2 cups of flour to make 12 cookies. If you want to make 30 cookies, how much flour do you need?"

Model's Reasoning: "First, I need to find out how much flour is needed per cookie. That's 2 cups / 12 cookies = 1/6 cup of flour per cookie. To make 30 cookies, I need to multiply the amount of flour per cookie by the number of cookies I want to make. So, the calculation is (1/6) * 30."
