Document Summary

Predictions of marginal utility theory: a fall in price of movies=> (leads to a change in quantity demanded of movie tickets)buy more movie tickets and less pop. If the price of movie tickets drop to 4 dollars The marginal utility per dollar of movie is larger than the marginal utility per dollar of pop. So we need to consume more movie tickets and less pop. ** the line through the 2 points(quantity demanded of movie tickets,price of movie tickets) is the demand curve of movie ticket. The price change results in a change in quantity demanded of the movie tickets. But the demand curve of pop will move leftward, because movie tickets and pop are substitutes for her: a rise in price of pop. The quantity demanded of pop will decrease and the demand for movie tickets will increase: a rise in income.
