Final answer:
Charging products for the costs that they use allows businesses to allocate expenses accurately and ensures that consumers who benefit from a product or service are the ones who pay for it.
Step-by-step explanation:
The benefit of charging products for the costs that they use versus the costs that they don't use is that it allows businesses to accurately allocate expenses and ensure that the consumers who benefit from a product or service are the ones who pay for it. By charging for the costs that they use, businesses can cover their expenses and continue to provide quality products and services. For example, if a business offers a subscription service with different tiers of usage, charging based on the costs that each tier incurs allows the business to provide more options and benefits to consumers who are willing to pay for them.
Moreover, charging for costs that are not used would lead to inefficiency and potentially increase the price of products for all consumers. If the costs of unused resources or services were included in the price, it would result in a higher overall expense for consumers without providing any additional value or benefit.
