Tom attends a party that collects $2000.  Half the school attended and the school had 400 people.  How much would they have made if 300 people attended?
There were 400/2=<T>divide(400, 2)=200.0 people in attendance
So that means each person paid 2000/200=$<T>divide(2000, 200)=10.0
So if 300 people attended they would have made 300*10=$<T>multiply(300, 10)=3000
