Coke would most likely make more profit, though would probably be sued as many students wouldn't be able to afford all of that coke. Some diabetic students would have nothing to drink. There would be no way for anyone to wash their hands. The school would be running out of plastic bags to put all of the students teeth in at the rate that they would be falling out.
Hope I helped!
Let me know if you need anything else!
