Final answer:
Advertising costs are typically fixed because they do not change in direct relation to production levels, unlike variable costs such as commissions, wages, and electricity for equipment, which fluctuate with business activity.
Step-by-step explanation:
The question asks for an example of a cost that is likely to have a fixed behavior pattern, meaning it remains constant regardless of the level of production or business activity. Among the options provided, c) Advertising cost is typically considered a fixed cost because a company will spend a certain amount on advertising that does not change in the direct relation to the number of items produced or sold. By contrast, sales force commissions, production labor wages, and electricity costs for packaging equipment are usually variable costs that go up or down depending on the level of production or sales.
Fixed costs are expenses that do not vary with the quantity of output produced. Examples include rent, machinery, and as mentioned, advertising. Understanding the distinction between fixed and variable costs is crucial for businesses to plan their expenses, price their products, and forecast profitability.
