- Find his average score for the first 5 games.
- After his fifth game, his average score increased by 4.9 points. Find his score for his sixth game.
(a)
Total score of first 5 games
= 110 + 170 + 167 + 118 + 108
= 673
Average score of first 5 games
= 673 ÷ 5
= 134.6
(b)
Average score of 6 games
= 134.6 + 4.9
= 139.5
Total score of 6 games
= 6 x 139.5
= 837
Score of Cody's sixth game
= 837 - 673
= 164
Answer(s): (a) 134.6; (b) 164
