- Find his average score for the first 4 games.
- After his fifth game, his average score increased by 1.9 points. Find his score for his fifth game.
(a)
Total score of first 4 games
= 146 + 166 + 134 + 180
= 626
Average score of first 4 games
= 626 ÷ 4
= 156.5
(b)
Average score of 5 games
= 156.5 + 1.9
= 158.4
Total score of 5 games
= 5 x 158.4
= 792
Score of Reggie's fifth game
= 792 - 626
= 166
Answer(s): (a) 156.5; (b) 166
