Amistad starts selling tickets to basketball games. They sell 292 tickets to the last game of the season. An adult ticket costs $3. A student ticket costs $1. They collect $470.00 in ticket sales. Write and solve a system of equations to find the number of each ticket sold.

a+s = 292
3a+1s = 470
2a = 178
a = 89
s = 203
check: 3*89 + 203 = 470
