solution

The soccer players took 15 cars in all.

explanation

Step 1
Use the clues to find out how many players were on each team.

  • One clue tells us that the Barracudas have 15 players.
  • The Sharks and Dolphins each have three fewer players than the Barracudas.
    (15 - 3 = 12)
    So the Sharks and the Dolphins must have 12 players each.
  • Find out how many players the Stingrays have.
    Think: There are 57 players in all. First find out how many players are on the other teams. Then subtract that number from 57.
    Add the total number of players on the other 3 teams.
  • 15 + 12 + 12 = 39
    57 – 39 = 18
    There were 18 players on the Stingrays.
Step 2 Make a chart to show the following information.
  • The number of players on each team
  • The number of players in each car
  • The number of cars each team took to the tournament

To find out how many cars the Sharks and Dolphins took to the tournament, list the possible combinations that can be multiplied to equal 12. Then guess and check to fit the clues.

Team Number of players on team Number of players in each car Number sentence showing number of cars Number of cars per team
Barracudas 15 3 15 players ÷ 3 people in
each car = 5 cars
5
Sharks 12 4 12 ÷ 4 = 3 3
Dolphins 12 3 12 ÷ 3 = 4 4
Stingrays 18 6 18 ÷ 6 = 3 3

Step 3
Add the number of cars for each team to find out the total number of cars the teams took to the soccer tournament.
     5 + 3 + 4 + 3 = 15; 15 cars in all
