Chalktown High School had their prom last weekend. There were 123 students who attended. If 3 students attended on their own, how many couples came to the prom?
There were 123 students – 3 single attendees = <T>subtract(123, 3)=120 students in couples.
120 students / 2 in a couple = <T>divide(120, 2)=60.0 couples.
