How should a consumer adjust their consumption of apples and oranges if the price of oranges rises, given their marginal utilities?

When the price of oranges rises, a consumer should think about how much satisfaction, or utility, they get from both apples and oranges. If oranges become more expensive, the consumer might find that they get less value from buying them compared to apples. To maximize their overall satisfaction, they should buy fewer oranges and increase their consumption of apples, which are now relatively cheaper. For example, if a consumer used to buy 5 oranges and 3 apples but finds that oranges now cost too much, they might decide to buy only 3 oranges and 5 apples instead, balancing their budget while still enjoying their fruit. This adjustment helps the consumer make the most of their money while still enjoying the fruits they like.
