Where does a buyer's demand curve come from? A rational buyer wants to get as much "bang per buck" from their consumption as possible. In economics, that's called marginal utility per dollar spent. When the price of a good decreases, the "bang per buck" on that good increases, which incentivizes consuming more of it. In this video, we derive the individual's demand curve for a good by tweaking the marginal utility per dollar spent. Created by Sal Khan.

Understanding economics, what some people call "economic literacy," is becoming essential for citizens in our national and increasingly interconnected world economy. Increasingly, productive members of society must be able to identify, analyze, and evaluate the causes and consequences of individual economic decisions and public policy including issues raised by constraints imposed by scarcity, how economies and markets work, and the benefits and costs of economic interaction and interdependence. Such literacy includes analysis, reasoning, problem solving, and decision making that helps people function as consumers, producers, savers, investors, and responsible citizens. - From the Michigan Grade Level Content Expectations
