The question is a principal is choosing between field trips. The final cost is \$600. The second costs \$240 plus \$40 per student. For what number of students is the first trip less expensive. I got the 1st trip would be less expensive with more than 9 students. Is this correct?
x= # of students
600<240+40x is how I set it up
-240 each side
260<40x
9<x
did I do it correctly

Looks good.
