Answer: 25
Step-by-step explanation:
To make 90 cookies, we would need 6 cups of flour.
The question at hand is a ratio problem.
We know that 60 cookies require 4 cups of flour. This means that for each cookie, we need 4/60 or 1/15 cup of flour.
To find out how much flour we need for 90 cookies, we simply multiply the amount of flour per cookie (1/15) by the number of cookies we want to bake, which is 90. So, 1/15 * 90 = 6. Thus, we would need 6 cups of flour to make 90 cookies.
