- Find his average score for the first 4 games.
- After his fifth game, his average score increased by 7.9 points. Find his score for his fifth game.
(a)
Total score of first 4 games
= 127 + 156 + 113 + 166
= 562
Average score of first 4 games
= 562 ÷ 4
= 140.5
(b)
Average score of 5 games
= 140.5 + 7.9
= 148.4
Total score of 5 games
= 5 x 148.4
= 742
Score of Albert's fifth game
= 742 - 562
= 180
Answer(s): (a) 140.5; (b) 180
