Alesia Allen went to the grocery store. 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?

• 4A + 6B = 3

  13.5A - 13B = 6

• A + B = 4

  A - B = 6

• 4A + 6B = 13

  3A + 7B = 13.5

• 4A - 6B = 13

  3A - 7B = 13.5
