    Word problem for dealing with systems of linear inequalities

    Please help me by checking to see if I set this word problem up right. . .

    Problem: 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.

    I got 20 > x + y and 92 < 7.5X + 6y

    Is this correct?
