Larry's Performance Pizza is a small restaurant in Chicago that sells gluten-free pizzas. Larry's very tiny kitchen barely has enough room for the two ovens in which his workers bake the pizzas. Larry signed a lease obligating him to pay the rent for the ovens for the next year. Because of this, and because Larry's kitchen cannot fit more than two ovens, Larry cannot change the number of ovens he uses in his production of pizzas in the short run. However, Larry's decision regarding how many workers to use can vary from week to week, because his workers tend to be students. Each Monday, Larry lets them know how many workers he needs for each day of the week. In the short run, these workers are (fixed/variable) inputs, and the ovens are (fixed/variable) inputs.
Larry's production schedule is presented in the following table. Fill in the blanks to complete the Marginal Physical Product of labor column for each worker.
