- Find his average score for the first 5 games.
- After his fifth game, his average score increased by 4.9 points. Find his score for his sixth game.
(a)
Total score of first 5 games
= 174 + 129 + 174 + 101 + 175
= 753
Average score of first 5 games
= 753 ÷ 5
= 150.6
(b)
Average score of 6 games
= 150.6 + 4.9
= 155.5
Total score of 6 games
= 6 x 155.5
= 933
Score of Gabriel's sixth game
= 933 - 753
= 180
Answer(s): (a) 150.6; (b) 180
