- Find his average score for the first 4 games.
- After his fifth game, his average score increased by 7.7 points. Find his score for his fifth game.
(a)
Total score of first 4 games
= 132 + 163 + 167 + 100
= 562
Average score of first 4 games
= 562 ÷ 4
= 140.5
(b)
Average score of 5 games
= 140.5 + 7.7
= 148.2
Total score of 5 games
= 5 x 148.2
= 741
Score of Fabian's fifth game
= 741 - 562
= 179
Answer(s): (a) 140.5; (b) 179
