Caitlin won a bag full of money! She has 49 bills in all. She counts $1,430. There are $20 dollar bills and $50 dollar bills. How many of each bill does Caitlin have?
WRITE a system where T= # of $20 and F = # of $50.

• T + F = 1430
  20T + 50F = 49
• T+ F = 49
  10T + 5F = 1430 
• T + F = 49
  20T + 50F  = 1430
• T + F = 49
  T + F = 1430

What is the solution?

• (1, -1)
• (-1, 1)
• (0, -2)
• (2, 0)

-8x < 48

• x < -6
• x > -6
• x < 6
• x > 6

What inequality does the number line graph represent?

• x > 4
• x > -4
• x < 4
• x >= -4
