- Find his average score for the first 4 games.
- After his fifth game, his average score increased by 0.099999999999994 points. Find his score for his fifth game.
(a)
Total score of first 4 games
= 140 + 169 + 107 + 146
= 562
Average score of first 4 games
= 562 ÷ 4
= 140.5
(b)
Average score of 5 games
= 140.5 + 0.099999999999994
= 140.6
Total score of 5 games
= 5 x 140.6
= 703
Score of Dylan's fifth game
= 703 - 562
= 141
Answer(s): (a) 140.5; (b) 141
