- Find his average score for the first 4 games.
- After his fifth game, his average score increased by 1.3 points. Find his score for his fifth game.
(a)
Total score of first 4 games
= 150 + 132 + 123 + 117
= 522
Average score of first 4 games
= 522 ÷ 4
= 130.5
(b)
Average score of 5 games
= 130.5 + 1.3
= 131.8
Total score of 5 games
= 5 x 131.8
= 659
Score of Flynn's fifth game
= 659 - 522
= 137
Answer(s): (a) 130.5; (b) 137
