- After his fifth game, his average score increased by 0.30000000000001 points. Find his score for his fifth game.
(a)
Total score of first 4 games
= 145 + 163 + 135 + 135
= 578
Average score of first 4 games
= 578 ÷ 4
= 144.5
(b)
Average score of 5 games
= 144.5 + 0.30000000000001
= 144.8
Total score of 5 games
= 5 x 144.8
= 724
Score of Albert's fifth game
= 724 - 578
= 146
Answer(s): (a) 144.5; (b) 146
