Final answer:

By setting up a proportion based on the given ratio of chocolate chips to cookies, it is determined that it takes 10 cups of chocolate chips to make 15 cookies.

Step-by-step explanation:

To solve this problem, we need to determine the proportion of chocolate chips needed per cookie and then scale it for 15 cookies. Since 8 cups of chocolate chips make 12 cookies, we can set up the following proportion:

8 cups / 12 cookies = x cups / 15 cookies

To find the unknown value 'x', which represents the cups of chocolate chips needed for 15 cookies, we cross multiply and solve for 'x':

(8 cups * 15 cookies) / 12 cookies = x cups

120 cups / 12 = x cups

x = 10 cups

Therefore, it takes 10 cups of chocolate chips to make 15 cookies.

Hello!!!

Answer:

11 cups of chocolate chips

Step-by-step explanation:

If we use the information we got from the problem we can see that 8 gives us 12. So all we need to do is add more to the orignal number(8) unitll we get 15. So 11 cups gives us 15 cookies.

Have a nice day!!!
