Rules

On the first day of college, the dean addresses the students pointing out some of the rules. "The female dormitory will be out-of-bounds for all male students, so too the male dormitory to the female students. Anybody caught breaking this rule will be fined $20 the first time. Anybody caught breaking this rule the second time will be fined $60. Being caught a third time will incur a hefty fine of $180. ARE THERE ANY QUESTIONS?".

A male student bashfully moves forward and asks: "How much for a seasonal pass?"
