Quizplus · Accepted Answer

Revealed preference theory implies that a consumer's preferences can be inferred from their actual choices. If the consumer chooses basket A over basket B when the cost is the same for both, it means that basket A is at least as good as basket B in the consumer's preference ranking. Therefore, the consumer must find basket A at least as good as basket B. Answer choices A and B suggest that basket A is better than basket B, but we cannot conclude that from the given information. Answer choice D suggests that the consumer may find basket B better than basket A, which contradicts the given information.
