- Find his average score for the first 5 games.
- After his fifth game, his average score increased by 2.9 points. Find his score for his sixth game.
(a)
Total score of first 5 games
= 152 + 110 + 161 + 148 + 177
= 748
Average score of first 5 games
= 748 ÷ 5
= 149.6
(b)
Average score of 6 games
= 149.6 + 2.9
= 152.5
Total score of 6 games
= 6 x 152.5
= 915
Score of Mark's sixth game
= 915 - 748
= 167
Answer(s): (a) 149.6; (b) 167
