JoAnn likes her job as a baby-sitter, but it pays only $5 per hour. She has been offered a job as a tutor that pays $12 per hour. Because it's summer, her parents insist she works a minimum of 20 hours per week. How many hours can JoAnn tutor and baby-sit and still make at least $90 per week? How much does she make?

• b + t > 20 
  5b + 12t > 90
• b + t > 20 
  5b + 12t < 90
• 5b + 12t > 20
  b + t < 90
• 5b + 12t < 20 
  b + t < 90
