As a first round conversation, we have been informed that the coffee pot will serve coffee and black tea. Both can be added sugar and cream. You will also have chocolate and cappuccino, with the only option to add sugar. Finally, a healthy green or white tea that can be topped with just milk will also work. Start modeling the coffee machine by entering the types to describe all these drinks.\n"]},{"cell_type":"markdown","metadata":{},"source":["### Coins\n","\n","At some point, a customer will enter a certain amount of each currency to purchase a product from the food vending machine.
