Set it up like a regular equation. I used:
[tex]3x+135 \ \textless \ 6x[/tex]

As you can see, however, I inserted the "less than" symbol rather than the equal sign because values greater than a certain value can also equal "x". Solve it like a normal equation and you will arrive at:

[tex]x \ \textgreater \ 45[/tex]

This means that, as long as x is greater than 45, "6x" will be greater than "3x+135". Thus, if you bring 46 students, the Science Center will cost less.
