Trevor tutors French for $15 and hour and scoops ice cream for $10 an hour. He is going to work 15 hours this week. How many hours does Trevor need to tutor to make at least $180? a0 hours
Total number of hours = 15 Let the hours spent tutoring french be x. Therefore hours spent on scooping ice cream = (15 - x) Amount: Tutoring french is $15 an hour, total for x hours = 15x For scooping ice cream it is $10 an hour 10*(15 - x) = 150 - 10x To make more than $180 15x + (150 - 10x) > 180 15x + 150 - 10x > 180 15x - 10x > 180 - 150 5x > 30 x > 30/5
