Which Product Will Generate the Most Money

I think that food would generate the most money out of the three product types.Because students might go there to get something that they cannot from the cafeteria or the vending machine. And there are items that you can get there that you can not get anywhere else for a cheaper price. People would go for the food items because the prices range from $0.50 to $2.25 meaning no matter what amount of money you have you could always get something.
