The school that Laura goes to is selling tickets to the annual talent show. On the first day of ticket sales the school sold 4 senior citizen tickets, 2 adult tickets and 5 child tickets for a total of $55. The school took in $67 on the second day by selling 7 senior citizen tickets, 2 adult tickets and 5 child tickets. On the third day the show earned $46 when they sold 2 senior citizen tickets, 4 adult tickets and 2 child tickets. What is the price each of one senior citizen ticket, one adult ticket and one child ticket?

Adult: $12 Child: $8 Senior: $8

I did not get any of the answers above so I am assuming none ofthe above.

Solve: -4x - 5y - z = 18 -2x - 5y - 2z = 12 -2x + 5y + 2z = 4

I did not get any of the answers above so I am assuming none of the above.
