Drugs & math do mix!

A math teacher in Manitoba has been suspended for putting together a math quiz that included the following question:

“Rufus is a pimp for three girls. If the price is $65 per trick, how many tricks per day must each girl turn to support Rufus’ $800 per day crack habit?”

(I wonder if the students had to assume he takes only a certain cut, say 60%, as opposed to taking all of his girls’ money? 🙂
