You can work at most 20 hours next week. You need to earn at least $92 to cover you weekly expenses. Your math tutoring job pays $7.50 per hour and your job as a pet sitter pays $6 per hour. You can work at most 7 hours tutoring. Write a system of linear inequalities to model the situation.

• s + t < 20
  6s + 7.50t ≥ 92
  t >7
• s + t ≤ 20
  6s + 7.50t ≥ 92
  t ≤ 7
