Skate Ranch charges $5.75 per skate session plus $8 for skate rental. Skate-a-roma charges $5.25 per skate session plus $9 for skate rental. Which system of equations can be used to represent the charges from the two skating rinks?

• y = 5.75x + 8

  y = 5.25x + 9

• y = 13.75x

  y = 14.25x

• y = 5.75x + 9

  y = 5.25x + 8

• y = 5.75x - 5.25

  y = 9x - 8
