LAS VEGAS—Exotic dancer Tricia "Mercedes" Hrlevich, 22, who is stripping to put herself through school, is failing her Red Rock Community College business classes, sources said Tuesday. "I definitely want to do something with, like, business," said Hrlevich, who has received Fs on three straight economics exams. "Dancing at Cheetah's [Gentlemen's Cabaret] is just a way of getting closer toward that goal." Hrlevich then accompanied a balding 54-year-old to the Champagne Room, where she earned $60 toward a Psych 101 textbook she will never read.
