In Dana's senior class, the 60% of 200 students is 0.6*200=<<0.6*200=120>>120 female students.
Fifty percent of the females, or 0.5*120=<<0.5*120=60>>60 of the female students were brunettes.
If 50% of the female brunettes were under 5 feet tall, then there were 60*0.5=<<50*.01*60=30>>30 female brunettes under five feet tall in Dana's senior class.
