12% of 120 is 14.4
Change the percentage into a decimal by dividing over 100:
12 / 100 = 0.12
Multiply:
0.12 × 120 = 14.4
$570.60 because 90/100=.90 so multiply that with 634 with .90 you get 570.60
Set it up like a regular equation. I used:

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:
<u>
</u>

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.
