Final answer:
The toothpaste commercial featuring Peyton Manning throwing a football likely has the least economic usefulness, as it does not provide practical information that aids consumers in making informed purchasing decisions, unlike ads for cars, restaurant specials, or medications.
Step-by-step explanation:
The scenario with the least amount of economic usefulness is likely the one with NFL player Peyton Manning throwing a football in a toothpaste commercial. This advertisement relies on the power of celebrity endorsement and the association of Manning's successful sports image with the toothpaste brand. However, unlike direct information about a car's features or medication's benefits and side effects, the connection between Manning's football skills and the efficacy of a toothpaste is tenuous, adding limited practical information for the consumer's decision-making process regarding the product's actual usefulness.
In contrast, detailed information about a vehicle's condition and features in an ad for a 2005 Volvo S60, the highlighting of special prices in a local restaurant's radio commercial, and the explanation of benefits and side effects of a new arthritis medication in a television commercial each provide more immediate and relevant utility to potential customers. These ads offer direct information pertaining to the quality, cost, and health impacts of the products and services, aiding consumers to make informed decisions grounded in their economic and personal needs.
