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. ]
