On the first day of college, the Dean addressed the students and outlined a key rule: "The female dormitory is off-limits to all male students, and the male dormitory is off-limits to female students. Anyone caught breaking this rule will be fined $20 for the first offense."
He continued, "A second offense will result in a $60 fine. Being caught a third time will incur a hefty fine of $180. Are there any questions?"
At this point, a male student in the crowd inquired, "How much for a season pass?"
