On the first day of college, the Dean addressed the
students, pointing out some of the rules:

“The female dormitory will be out-of-bounds for all
male students, and the male dormitory to the female
students. Anybody caught breaking this rule will be
fined $20 the first time.” He continued, “Anybody
caught breaking this rule the second time will be
fined $60. Being caught a third time will cost you
a fine of $180. Are there any questions?”

At this point, a male student in the crowd inquired:
“How much for a season pass?”
