Answer: C

Solution:

Let n be the number of games the team played before the final game. We can create the equation:

34 = (35n + 28)/(n + 1)

34n + 34 = 35n + 28

6 = n

So the team played n + 1 = 7 games.

Let the number of football matches before the final match be \(n\)

Total points \(= 35\cdot n\)

Total points after final match \(= 35\cdot n +28 = 34(n+1) \Rightarrow 35n +28 = 34n+34 \Rightarrow n = 6\)

Therefore, the total matches after final match \(= n +1 = 6 +1 =7\).
