Seth played 6 games of bowling. His scores for the first 5 games were 152, 141, 103, 173 and 105 points respectively.
- Find his average score for the first 5 games.
- After his fifth game, his average score increased by 1.7 points. Find his score for his sixth game.
(a)
Total score of first 5 games
= 152 + 141 + 103 + 173 + 105
= 674
Average score of first 5 games
= 674 ÷ 5
= 134.8
(b)
Average score of 6 games
= 134.8 + 1.7
= 136.5
Total score of 6 games
= 6 x 136.5
= 819
Score of Seth's sixth game
= 819 - 674
= 145
Answer(s): (a) 134.8; (b) 145
