On the first day of a music concert, the price of 12 adult tickets and 4 child tickets is 84$. The second day the concert made 78$ by selling 6 adult tickets and 14 child tickets. Find the price of an adult ticket and the price of an child ticket.
Total tix sold = 12 + 4 + 6 + 14 = 36
12 A + 4 C = $ 84
6 A + 14 C = $ 78 multiply THIS equation by -2
-12 A - 28 C = - 156 and add to the first equation
- 24 C = -72
C = 3 Now you should be able to find A ...the price of Adult tix.....(sub the value of A into oneof the eqautions)
