Final answer:
The correct conclusion from the prospect's statement is that they are interested in the product but cannot afford it due to budget constraints. The decision-making process is aligned with the concepts of marginal utility and opportunity cost, showing the influence of the law of demand.
Step-by-step explanation:
When a prospect says, "It sounds good, and we do need it, but we just can't afford it right now," you would conclude from this statement that the prospect is interested but has budget constraints. This indicates that while the need and the desire for the product exist, financial limitations are preventing the purchase at the current time. Understanding the concept of marginal utility and opportunity cost is essential in this context. A rational consumer, such as Alphonso in our example, will only purchase additional units of a product so long as the utility gained from that unit exceeds the cost of what must be given up (opportunity cost). As Alphonso buys more bus tickets, the utility he receives from each additional ticket decreases, while the cost (the burgers he has to forego) increases. He will stop purchasing tickets when the utility of an additional bus ticket is just equal to what he has to give up for it. This decision is influenced by the pricing and income levels, verifying that the law of demand is a strong influence on whether or not a consumer will decide to make a purchase.
