Paul played 6 games of bowling. His scores for the first 5 games were 135, 155, 148, 128 and 116 points respectively.
- Find his average score for the first 5 games.
- After his fifth game, his average score increased by 7.1 points. Find his score for his sixth game.
(a)
Total score of first 5 games
= 135 + 155 + 148 + 128 + 116
= 682
Average score of first 5 games
= 682 ÷ 5
= 136.4
(b)
Average score of 6 games
= 136.4 + 7.1
= 143.5
Total score of 6 games
= 6 x 143.5
= 861
Score of Paul's sixth game
= 861 - 682
= 179
Answer(s): (a) 136.4; (b) 179
