The Grade 8 students had a graduation dinner. They paid a flat rate of $125 for the use of the hall, plus $13 for each student who attended. The total cost of the dinner was $944. How many students attended the dinner?

First you take 125 away from 944 because that will be paid regardless of how many students there are so 944-125=819 then each student costs $13 so you do $819 divided by the cost for each student so 819/13 = 63 so 63 students attended
