Final answer:
To make 30 cookies, 1.25 cups of flour are required, based on the proportional increase from the original recipe that uses 1 cup of flour to make 24 cookies.
Step-by-step explanation:
To calculate how many cups of flour are needed to make 30 cookies, we use a proportional relationship based on the original recipe which provides a ratio of cups of flour to the number of cookies. If 1 cup of flour is used to make 24 cookies, we need to find out how much flour will be required for 30 cookies.
We set up a proportion where 1 cup of flour/24 cookies = x cups of flour/30 cookies. Solving for x gives us:
24 * x = 1 * 30
x = 30 / 24
x = 1.25
Therefore, 1.25 cups of flour are needed to make 30 cookies.
