- Find his average score for the first 5 games.
- After his fifth game, his average score increased by 6.7 points. Find his score for his sixth game.
(a)
Total score of first 5 games
= 135 + 150 + 103 + 123 + 153
= 664
Average score of first 5 games
= 664 ÷ 5
= 132.8
(b)
Average score of 6 games
= 132.8 + 6.7
= 139.5
Total score of 6 games
= 6 x 139.5
= 837
Score of Jeremy's sixth game
= 837 - 664
= 173
Answer(s): (a) 132.8; (b) 173
