Hi  

2A + 3C = $62

3A + 4C = $87 

6A + 9C = $186     |1ST EQ X 3 

6A + 8C = $174    |2ND EQ X 2

6A + 9C = $186  

-6A - 8C = - $174  

Child = $12 per ticket

2A = $62 - $36 = $26   1ST EQ

2A = $ 26

Adult = $13 per ticket

CHECKING our answer*** 2ND EQ

$39 + $48 = $87   CHECKS!

 Wish You the Best in your Studies.
