Julio's school is selling tickets to the annual dance competition. On the first day of ticket sales the school sold 2 senior citizen tickets and 13 child tickets for a total of $172. The school took in$220 on the second day by selling 8 senior citizen tickets and 13 child tickets. What is the price each of one senior citizen ticket and one child ticket?
