Verified step by step guidance

1. Understand the concept of willingness to pay (WTP), which is the maximum amount a consumer is ready to pay for a good or service based on the value they place on it.
2. Recognize that consumer surplus is the difference between the consumer's willingness to pay and the actual market price they pay for the good.
3. Formulate consumer surplus as: \(\text{Consumer Surplus} = \text{Willingness to Pay} - \text{Price}\).
4. Determine that a purchase is considered a good deal if the consumer surplus is positive, meaning the willingness to pay exceeds the price.
5. Conclude that the consumer should buy the good only if \(\text{Willingness to Pay} > \text{Price}\), as this maximizes their benefit from the transaction.
