Tickets to a movie cost $7.25 for adults and $5.50 for students. A group of friends purchased 8 tickets for $52.75. How many adult tickets and student tickets were purchased?

Have you tried using algebra?
A + S = 8
725 A + 550 S = 5275
Solve those equations for A and S.
Hint: subsitute 8S for A in the second equation
