- 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
= 112 + 116 + 121 + 141
= 490
Average score of first 4 games
= 490 ÷ 4
= 122.5
(b)
Average score of 5 games
= 122.5 + 0.099999999999994
= 122.6
Total score of 5 games
= 5 x 122.6
= 613
Score of Dylan's fifth game
= 613 - 490
= 123
Answer(s): (a) 122.5; (b) 123
