Let 'x' represents the cost of the ticket for an adult, and 'y' be the cost of a child's ticket.
Andrew's family spend 410 on two adult tickets.
[tex]2x=410[/tex]From the above expression,
[tex]\begin{gathered} x=\frac{410}{2} \\ =205 \end{gathered}[/tex]Thus, the cost of an adult ticket is 205.
Given that the Max's family spend 375 for 3 tickes, and two of them is for childrens.
[tex]\begin{gathered} x+2y=375 \\ 205+2y=375 \\ 2y=375-205 \\ 2y=170 \\ y=\frac{170}{2} \\ y=85 \end{gathered}[/tex]Thus, the cost for tickets for the childrens is 85.
