A concert brings in $1148 in ticket sales. Regular tickets cost $8, while student tickets cost $5.

Question

A total of 172 tickets were sold. How many regular tickets and student tickets were sold? Set up the equation with one unknown variable. DO NOT SOLVE.

Answer 1

Here's what we know:

8r + 5s = 1148

r + s = 172

 

This can be solves by elimination process (multiplying the second equation to create a -8r or -5s and subtracting the second equation from the first).
