- 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
= 113 + 151 + 147 + 163
= 574
Average score of first 4 games
= 574 ÷ 4
= 143.5
(b)
Average score of 5 games
= 143.5 + 1.9
= 145.4
Total score of 5 games
= 5 x 145.4
= 727
Score of Flynn's fifth game
= 727 - 574
= 153
Answer(s): (a) 143.5; (b) 153
