Felix's Performance Pizza is a small restaurant in New York City that sells gluten-free pizzas. Felix's very tiny kitchen has barely enough room for the four ovens in which his workers bake the pizzas. Felix signed a lease obligating him to pay the rent for the four ovens for the next year. Because of this, and because Felix's kitchen cannot fit more than four ovens, Felix cannot change the number of ovens he uses in his production of pizzas in the short run. However, Felix's decision regarding how many workers to use can vary from week to week because his workers tend to be students. Each Monday, Felix lets them know how many workers he needs for each day of the week. In the short run, these workers are inputs, and the ovens are inputs.
