Answer:
15. the answer is "Omar would have 3 cups of cornmeal left"
Explanation:
this is because you have 5 cups of cornmeal, you need to make 24 muffins and 1/2 of a cup makes 6 muffins. 24 divided by 6 equals 4 and 1/2 times four equals 2. therefor, you would only need 2 cups of cornmeal to make 24 muffins, which in the end leaves him with 3 cups left.
