If a consumer is maximizing utility, how should they allocate their budget between apples and oranges?

When a consumer is maximizing utility, they need to think about how much happiness or satisfaction they get from each fruit, which is called marginal utility. The consumer should compare the marginal utility of apples to that of oranges in relation to their prices. For example, if one apple gives you 10 units of happiness and costs $1, while one orange gives you 5 units of happiness and also costs $1, you get more satisfaction per dollar from apples. To maximize utility, the consumer should spend more of their budget on apples until the point where the extra happiness from the last apple equals the happiness from the last orange. This way, they make sure they are getting the most enjoyment from their money spent on fruit.
