Question

Each team in a soccer leaguehas played every other team 5 times. Current league standings are:

Team A 37 Points
Team B 34 Points
Team C 28 Points
Team D 26 Points
Team E 20 Points

If a team receives 3 points for a win, 1 point for a tie, and 0 points for a loss, how many of the games ended in a tie?

Thanks for any suggestions.
