Team Travel 

The 57 players on four soccer teams traveled to a soccer tournament in Plainville.
Each car carrying the members of the same team had the same number of players in it.
 The 15 players on the Barracudas rode three to a car.
 The Sharks and the Dolphins had three fewer players on each team than the Barracudas had.
 In an odd number of cars, the Sharks had one more player in each car than the Dolphins.
 The Stingrays had six players per car.
In all, how many cars did the soccer players take to the tournament?
