the price of the ticket which Disney on ice would make no money at all is:
[tex](x-8)(450-3x)=0[/tex]and here, are two posible solutions:
[tex]\begin{gathered} 1)x-8=0 \\ 2)450-3x=0 \end{gathered}[/tex]for the first one 1)
[tex]x=8[/tex]for the second one 2)
[tex]\begin{gathered} 450=3x \\ \frac{450}{3}=x \\ 150=x \end{gathered}[/tex]and in this problem the realistic answer is the first one, so the solution is $8 dollars
