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
Thanks for checking my answer

Looks good.
