Marginal utility is the change in total utility from consuming one additional unit. From 2 to 3 tickets, total utility increases from 90 to 110, a change of 20. The question incorrectly states the marginal utility falls by a certain amount, but it actually asks for the change in marginal utility. From 1 to 2 tickets, the change in utility is 30 (90-60), and from 2 to 3 tickets, it's 20 (110-90). The decrease in marginal utility from the second to the third ticket is 10 (30-20), not the change in total utility, which is a misunderstanding in the question's phrasing.
