Hi,

The cost of a child's ticket was $3 less than the cost of an adults ticket.

Let x and (x-3)represent the cost of the adult and a child's ticket respectively

Question states*** 9 adults and 2 children, total cost was $181

 9x + 2(x-3) = $181

    11x = $187

      x = $17, price of an adult ticket.  the child's ticket cost $14

 9%2A17+%2B+2%2A14+=+181
