John is selling tickets to an event. Attendees can either buy a general admission ticket, x, or a VIP ticket, y. The general admission tickets are $80 and the VIP tickets are $85. If he knows he sold a total of 26 tickets and made $2,155, how many of each type did he sell? Enter a system of equations to represent the situation, then solve the system. The system of equations is . John sold general admission tickets and VIP tickets.

Step-by-step explanation:

x+y=26

80x + 85y = 2155

y = 26-x

80x + 85(26-x) = 2155

80x + 2210 - 85x = 2155

-5x = -55

x = 11

11+y = 26

y = 15
