Nancy went to the grocery story.  On Monday she purchased 4 apples and 6 bananas for a total of $13.  On Wednesday she purchased 3 apples and 7 bananas for a total of $13.50.  Which system of equations represents the situation?

• 4x + 6y = 3
  13.5x - 13y = 6
• x + y = 4
  x - y = 6
• 4x + 6y = 13
  3x + 7y = 13.5
• 4x - 6y = 13
  3x - 7y = 13.5

A phone company offers two monthly plans.

Plan A costs $20 plus an additional $0.12 for each minute of calls. Plan B costs $12 plus an additional $0.15 for each minute of calls.

What is the proper system of equations?

• y = 0.12x + 20

  y = 0.15x + 12

• y = 20x + 0.10

  y = 12x + 0.12

• y = 12x + 20

  y = 0.15x + 0.12

• y = 0.15x + 20

  y = 0.12x + 12
