messages.content: Of 100 people in attendance at the school dance, 10% were school faculty and staff, or a total of 0.1*100=<<100*0.1=10>>10 people.
  This leaves 100-10=<<100-10=90>>90 students in attendance.
  Of the remaining attendees, two-thirds were girls, or (2/3)*90=<<(2/3)*90=60>>60 attendees were girls.
  Thus, the remaining 90-60=<<90-60=30>>30 students were boys who attended the school dance.
