Budget line (video) | Consumer theory | Khan Academy
We can actually substitute these numbers in here and then we can actually plot what essentially this budget line will look like. In our situation, 20, Y = 20, the price of chocolate is equal to 1.
Optimal point on budget line (video) | Khan Academy
The budget line shows all possible combinations of two goods a consumer can purchase if the entire income is spent. The equilibrium of the indifference curve is at the point at which the …
The Production Possibilities Frontier (article) | Khan Academy
The budget constraint is typically illustrated graphically as a straight line or curve in a two-dimensional space representing different combinations of goods or services that can be …
Indifference curves and marginal rate of substitution
Budget lines show all of the different combinations of two goods that are affordable. Along a single budget line, the prices of each good are not changing and income is not changing, only the …
Types of indifference curves (video) | Khan Academy
You need to know a little calculus to calculate the optimum point. The trick is that at the optimum point the slope of the budget line and the slope of the indifference curve is the same. Thus, …
Utility maximization: equalizing marginal utility per dollar
Each of these approaches provides a way to determine how to maximize total utility based on your preferences, constraints, and available information, without explicitly drawing a graph.
Interpretation of Lagrange multipliers (article) | Khan Academy
You can get a feel for this problem using the following interactive diagram, which let's you see which values of (h, s) yield a given revenue (blue curve) and which values satisfy the …
