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?"
