- Find his average score for the first 4 games.
- After his fifth game, his average score increased by 7.1 points. Find his score for his fifth game.
(a)
Total score of first 4 games
= 161 + 100 + 160 + 141
= 562
Average score of first 4 games
= 562 ÷ 4
= 140.5
(b)
Average score of 5 games
= 140.5 + 7.1
= 147.6
Total score of 5 games
= 5 x 147.6
= 738
Score of Jenson's fifth game
= 738 - 562
= 176
Answer(s): (a) 140.5; (b) 176
