- Find his average score for the first 4 games.
- After his fifth game, his average score increased by 6.9 points. Find his score for his fifth game.
(a)
Total score of first 4 games
= 152 + 153 + 136 + 113
= 554
Average score of first 4 games
= 554 ÷ 4
= 138.5
(b)
Average score of 5 games
= 138.5 + 6.9
= 145.4
Total score of 5 games
= 5 x 145.4
= 727
Score of Daniel's fifth game
= 727 - 554
= 173
Answer(s): (a) 138.5; (b) 173
