- Find his average score for the first 5 games.
- After his fifth game, his average score increased by 3.9 points. Find his score for his sixth game.
(a)
Total score of first 5 games
= 113 + 164 + 168 + 152 + 111
= 708
Average score of first 5 games
= 708 ÷ 5
= 141.6
(b)
Average score of 6 games
= 141.6 + 3.9
= 145.5
Total score of 6 games
= 6 x 145.5
= 873
Score of Albert's sixth game
= 873 - 708
= 165
Answer(s): (a) 141.6; (b) 165
