tray. A pretty good game you could make between 60-100 bucks. Half of that was probably in tips, the older people on the West Side definitely tipped better than the students on the East Side. (Just had to throw that in.) So let's say I sold an average of 20 trays per game. That's 400 Cokes per game. Multiply that by the 50 other kids doing the same thing. That's 20k Cokes per game. Multiply that by 6 games. I would guess somewhere between 120-200k Cokes per year. Don't even get me started on the year or two we switched to Pepsi, or the infamous misprinting of the cups that read Go Hoakies!
