Answer to Question 1

FALSE

Answer to Question 2

The marginal utility from his last concert is 200 units. In order for Ricardo to maximize his utility, the marginal utility per dollar must be equal for all goods. The marginal utility per dollar from the last DVD is (20 units)  (4 ) = 5. So the marginal utility per dollar from the last concert also must equal 5, which, given its price of 40, means that concert has a marginal utility of 200, because (200 units)  (40 ) = 5.
