he played 6 games and scored 84 points, you need to find out how many points he scores in 1 game. You can make a proportion:
[tex] \frac{ 6\: games}{84 \: points} = \frac{1 \: game}{x \: points} [/tex]
[tex]x = \frac{84 \times 1}{6} = 14[/tex]
so on average he does 14 points per game
answer: 14 points
