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
