Question

Quizplus · Accepted Answer

At the best affordable point, the consumer maximizes utility by choosing a combination of goods where the slope of the indifference curve equals the slope of the budget line. This is because the slope of the budget line represents the rate at which the consumer can trade one good for another (i.e. the opportunity cost) and the slope of the indifference curve represents the rate at which the consumer is willing to trade one good for another (i.e. the marginal rate of substitution). At the point where these two slopes are equal, the consumer is buying the goods in the most efficient way possible and any other combination of goods would result in less utility.
