Tickets to a show cost$10 in advance and $15 at the door. If 120 Tickets were sold for a total of $1390, how many of the tickets were bought in advance?
Answered by PsyDAG
Let x = advance and y = at door.

x = 120 - y

10x + 15y = 1390

Substitute 120-y for x in second equation and solve for y. Insert that value into the first equation and solve for x. Check by inserting both values into the second equation.
