- Find his average score for the first 5 games.
- After his fifth game, his average score increased by 2.7 points. Find his score for his sixth game.
(a)
Total score of first 5 games
= 164 + 101 + 173 + 153 + 173
= 764
Average score of first 5 games
= 764 ÷ 5
= 152.8
(b)
Average score of 6 games
= 152.8 + 2.7
= 155.5
Total score of 6 games
= 6 x 155.5
= 933
Score of Oscar's sixth game
= 933 - 764
= 169
Answer(s): (a) 152.8; (b) 169
