c+a=146

5c+8a=1036

c-a=146

8c+5a=1036

c+a=1036

8c+5a=146

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
