Sam's FootballLevel pending
Sam had never fully understood the points system in football, and felt that the scoring of goals should be encouraged. His idea is that 10 points should be awarded for a win, 5 points for a draw and 1 point for each goal scored, whatever the result of the match.
This was tried with three teams, A, B and C. Each team played 2 matches scored at least one goal in every match. A scored 22 points, B 17 points and C scored 9 points.
Find the score in the match between A and B.
[The point system are like this, if A won C 3-1, A would get 10 points for the win and 3 points for the goals scored. C would get 1 point for the loss and 1 point for the goal scored. ]
