Choose the equation and the inequality needed to answer this question. Trevor tutors French for $15 and hour and scoops ice cream for $10 an hour. He is going to work 15 hours this week. At least how many hours does he need to tutor to make more than $180? Let x equal the number of hours he tutors and y be the number of hours he scoops ice cream. x + y = 15 x + y > 15 x + y < 15 15x + 10y = 180 (I think this one, I don't know the other one) 15x + 10y ≥ 180 15x + 10y ≤ 180 Then this question goes with it: At least how many hours does Trevor need to tutor to make more than $180?
