Simon played 6 games of bowling. His scores for the first 5 games were 131, 138, 105, 131 and 151 points respectively.
- Find his average score for the first 5 games.
- After his fifth game, his average score increased by 5.3 points. Find his score for his sixth game.
(a)
Total score of first 5 games
= 131 + 138 + 105 + 131 + 151
= 656
Average score of first 5 games
= 656 ÷ 5
= 131.2
(b)
Average score of 6 games
= 131.2 + 5.3
= 136.5
Total score of 6 games
= 6 x 136.5
= 819
Score of Simon's sixth game
= 819 - 656
= 163
Answer(s): (a) 131.2; (b) 163
