On the first day of college, the Dean addressed the students:
“The female dormitory is 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.
The second time you will be fined $60.
And third time will cost you a fine of $180.
Are there any questions?”
A male student inquired, “How much for a season pass?”
