- After his fifth game, his average score increased by 0.69999999999999 points. Find his score for his fifth game.
(a)
Total score of first 4 games
= 180 + 174 + 132 + 112
= 598
Average score of first 4 games
= 598 ÷ 4
= 149.5
(b)
Average score of 5 games
= 149.5 + 0.69999999999999
= 150.2
Total score of 5 games
= 5 x 150.2
= 751
Score of George's fifth game
= 751 - 598
= 153
Answer(s): (a) 149.5; (b) 153
