Final answer:
The claim that a business has only one revenue driver when selling a product and a service guarantee is false. Such a business has multiple revenue drivers, as both the product and the service contribute to the total revenue.
Step-by-step explanation:
The statement that if a business sells a single product plus a service guarantee, it only has one revenue driver is false. The business in fact has two revenue drivers: the product and the service guarantee. Tying sales, which is a situation where a customer is allowed to buy one product only if the customer also buys another product, illustrates that in such a bundle there are inherently two separate components contributing to the revenue.
Furthermore, every business aims to earn a profit, which is calculated as Profit = Total Revenue - Total Cost. The inclusion of a service guarantee as a separate component could affect both the total revenue and total cost, indicating multiple factors are driving the business's profitability.
Additionally, the concept of real GDP, which depends on the overall demand for goods and services, further supports that there can be multiple revenue drivers within a business based on differing demands for each offering.
