The document discusses the relationship between price and utility for consumers. It explains that a consumer's willingness to pay decreases for each additional unit of a commodity as the marginal utility declines. The consumer will purchase units as long as the marginal utility is greater than the price, and will stop purchasing once the marginal utility and price become equal. This is illustrated in a table showing marginal utility decreasing for each additional unit while price remains constant, with consumption stopping at the point where marginal utility and price are equal. A second document defines consumer surplus as the difference between what consumers are willing to pay versus what they actually pay, which occurs when willingness to pay is greater than the market price.
