Final answer:
The question is about finding the total utility at equilibrium for goods J and K given a consumer's budget and the prices of the goods. Without additional details on the consumer's preferences or utility functions, it is not possible to provide an exact value for total utility.
Step-by-step explanation:
The question is about determining the total utility realized from the consumption of goods J and K, given a consumer's budget and the prices of the goods. Based on the information provided, we know the income is $52, and the goods J and K have prices of $8 and $4, respectively. Equilibrium is reached when the consumer has allocated their budget in a way that maximizes their utility, with the marginal utility per dollar spent being equal across all goods they purchase. Unfortunately, without additional information such as the consumer's preferences, the specific quantities of J and K that maximize utility, or the utility values themselves, we cannot calculate the exact total utility.
The provided information about the demand curve and consumer surplus, along with examples involving quantities and prices of different points, help us to understand concepts of market equilibrium, but they do not directly help in calculating total utility without the utility function or preference data for goods J and K.
Finding equilibrium utility involves understanding the consumer's choices in the context of their budget constraint and the prices of the goods. The question seems to be aiming for a conceptual understanding of consumer surplus and how a consumer achieves equilibrium utility, rather than a specific numeric answer.
