Jerry is tired of how much food Kramer eats and doesn’t pay for, but Kramer has offered to keep a tab for himself and will write down every time he consumes something so he can pay Jerry back. Jerry discovers a half full can of soda in the fridge and asks Kramer if it’s his, but Kramer believes he can purchase just half a can of soda. Jerry has to explain to him that items like soda and fruit have to purchased in discrete units, not continuous units.
Thanks to Daniel Stone for the suggestion!
#Useinclass for teaching discrete vs continuous vars:
"You cannot buy half a can of soda!"https://t.co/CI094tp0FS@EconMedia
