Final answer:
A consumer can spend extra money to get extra utility or satisfaction by spending more, depending on the concept of consumer surplus.
Step-by-step explanation:
A consumer can indeed spend extra money to get extra utility or satisfaction by spending more, but it's important to note that this statement is not always true. It depends on the concept of consumer surplus, which is the additional benefit that consumers derive from paying a price lower than what they are willing to pay. To explain this further, let's use an example:
Imagine a tablet that is priced at $80, and there is a demand curve that shows the different quantities consumers are willing to pay for at different prices. If the price were to be increased to $90, the demand for the tablets would decrease, and only 20 million tablets would be sold. However, those consumers who were willing to pay $90 but were able to pay only $80 will experience consumer surplus. This surplus is the difference between what they were willing to pay ($90) and what they actually paid ($80), resulting in additional utility or satisfaction beyond what they had to pay.
