Final answer:
Iyana's store employees at the pizza parlor are variable inputs, while the pizza ovens are fixed inputs. Employees can be adjusted weekly, but the number of ovens cannot change due to lease terms.
Step-by-step explanation:
In the scenario described for Iyana's Pizzas, the store employees are variable inputs because Iyana can change the number of employees each week depending on the need. The pizza ovens, in contrast, are fixed inputs as the number can't be altered in the short run due to the lease and physical constraints.
Variable inputs in a business are those that can be adjusted quickly and with relative ease to match the production needs, such as labor and raw materials. In Iyana's case, she can hire or schedule more or fewer employees based on anticipated demand. Fixed inputs, like the pizza ovens, are those assets that cannot be readily adjusted; changes to these often require significant time or capital investment.
In summary, Iyana has flexibility in manipulating her labor force to match business demands but is restricted when it comes to altering the number of pizza ovens due to her current lease agreement.
