Dave has $300 to spend each month on pizzas and streaming movies. Pizzas and movies both have a price of $10, and Dave is maximizing his utility by buying 20 pizzas and 10 movies. Suppose Dave still has $300 to spend, but the price of movies rises to $20, while the price of pizzas drops to $5. Is Dave better or worse off than he was before the price change? Use a budget constraint–indifference curve graph to illustrate your answer.
