Question 1156682: The county fair charges $4 for adult tickets and $3 for student tickets. The Frank family purchased a total of 9 tickets for $31. Write a system of equations that could be used to find a, the number of adult tickets, and s, the number of student tickets the Frank family purchased.

You can put this solution on YOUR website! .
a + s = 9 (counting tickets)
4a + 3s = 31 (counting money)
Writing the setup equations for such problems is traditionally considered as very simple, routine step.
-----------------
It is a standard tickets problem.
There are different methods of solving such problems. See the lessons
