A buffet has an all-you-can-eat ice cream station. The buffet receives ice cream in 400 ml containers, and only provides 70 ml cups for customers to get ice cream to save money.
The user enters the number of trips to the ice cream station to get only 1 cup per trip and the app will calculate the number of containers of ice cream the user will consume.
The app will round the number of containers consumed to the next integer to show the number of containers opened.
