Jesper is a person who wants sushi, he has a budget of 20,95 euro's and wants the best eating experience. To find out how he will get the best experience, I have to make an Integer Linear Program (ILP), but I struggle with the integer part... Also for some weird reason he is only allowed to buy one of each item.

This is the data
