Final answer:
To make 12 waffles, you would need 9 cups of mix.
Step-by-step explanation:
To find out how much mix you would need to make 12 waffles, you can set up a proportion using the given information. The recipe uses 3 cups of mix for 4 waffles, so we can set up the proportion:
3 cups / 4 waffles = x cups / 12 waffles
Now we can cross multiply and solve for x:
4x = 3 * 12
4x = 36
x = 36 / 4
x = 9
So, you would need 9 cups of mix to make 12 waffles.
