Final answer:
In the short run, fixed costs such as rent remain unchanged regardless of the quantity of production. Wages to labor and material costs are variable costs, adjusting with production levels.
Step-by-step explanation:
The examples of short-run fixed costs include expenditures that do not change with the level of production. Rent is a perfect example of a short-run fixed cost since it remains constant regardless of how much is produced, as long as the terms of the lease are in effect. Other costs like bonds and interest might have fixed payments, but they are financial costs rather than costs directly related to production capacity. Conversely, wages to labor and material costs are considered variable costs because they change with the amount of production.
