- Find his average score for the first 4 games.
- After his fifth game, his average score increased by 1.9 points. Find his score for his fifth game.
(a)
Total score of first 4 games
= 155 + 164 + 175 + 148
= 642
Average score of first 4 games
= 642 ÷ 4
= 160.5
(b)
Average score of 5 games
= 160.5 + 1.9
= 162.4
Total score of 5 games
= 5 x 162.4
= 812
Score of Owen's fifth game
= 812 - 642
= 170
Answer(s): (a) 160.5; (b) 170
