Understanding Budget Constraints and Opportunity Costs

The video tutorial covers budget constraints, opportunity costs, and the law of diminishing marginal utility. It uses example problems to illustrate how to calculate the maximum number of items that can be purchased within a budget, how to draw a budget constraint graph, and how to understand opportunity costs. The tutorial also explains the concept of diminishing marginal utility, showing how the utility of additional units decreases as more are consumed.

• 5

• 6

In a budget constraint graph, what does the slope represent?

• Maximum quantity

What happens to marginal utility as more of a product is consumed?

• It doubles

• It remains constant

• It decreases

• It increases

How does an increase in the price of coffee affect the budget constraint graph?

• The graph rotates clockwise

• The graph shifts right

• The graph shifts left

• The graph rotates counterclockwise

What is the effect on the graph if the price of a sandwich decreases?

• The y-intercept moves up

• The y-intercept moves down

• The x-intercept moves left

What happens to the budget constraint line when the budget increases?

• It extends outward
