Write and solve a system of equations for each situation.

1.Your school sells tickets for its winter concert. Student tickets are $5 and adult tickets are $10. If your school sells 85 ticket and makes $600, how many of each ticket did they sell?
-Could someone tell me how to write the equations? Thanks

Work with the number of tickets, and then with the amount of money.

s + a = 85
5s + 10a = 600
a=35

s=50
