Final answer:
Fixed costs are business expenditures that stay constant regardless of production levels, such as rent, machinery costs, and long-term advertising.
Step-by-step explanation:
Fixed costs are expenditures associated with the fixed inputs of a business. These costs do not change with variations in the amount of production or services provided. Common examples of fixed costs include rent on a factory or retail space, cost of machinery or equipment, research and development costs, and long-term advertising campaigns. This concept applies across various businesses, from manufacturing computer chips, which incurs significant fixed costs for factory infrastructure, to a local moving company that may have minimal fixed costs if it rents vehicles as needed.
