TOTAL REVENUE AND TOTAL COST: A profit-maximizing firm produces output where the difference between total revenue and total cost, that is economic profit, is the greatest. This total revenue and total cost approach to identifying profit-maximizing production can be accomplished using either a table of numbers of a set of curves. However, the end result is the same. Profit-maximizing production takes place at the quantity generating the greatest difference between total revenue and total cost. An added benefit of performing the analysis with curves, however, is the observation that profit-maximizing production occurs where the slopes of the total revenue and total cost curves are equal.

MARGINAL UTILITY AND DEMAND An explanation of the law of demand and the negatively-sloped demand curve based on utility analysis and the law of diminishing marginal utility. The law of diminishing marginal utility states that marginal utility declines as consumption increases. Because demand price depends on the marginal utility obtained from a good, price also declines as consumption increases, meaning price and quantity demanded are inversely related, which is the law of demand.
