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
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?"
