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