On the first day

On the first day of college, the Dean addressed the students, pointing out some of the rules, saying, “The female dormitory will be out-of-bounds for all male students, and the male dormitory to the female students. Anyone caught breaking this rule once will be fined $50.” He continued, “Anyone caught breaking this rule a second time will be fined $150. Being caught a third time will incur a hefty fine of $400. Are there any questions?” At this point, a male student in the crowd inquired, “How much for a season pass?”
