PLEASE HELP!!
You can work at most 20 hours next week. You need to earn at least $92 to cover your weekly expenses. Your dog - walking job pays $7.50 per hour and your job as a car wash attendant pays $6 per hour. Write a system of linear inequalities to model the situation.
7.50x + 6y < 92. AND x + y > 20
7.50x + 6y > 92. AND. x + y < 20
7.50x + 6y ≥ 92. AND. x + y ≤ 20
7.50x + 6y ≤ 92. AND. x + y ≥ 20
