- Find his average score for the first 5 games.
- After his fifth game, his average score increased by 2.7 points. Find his score for his sixth game.
(a)
Total score of first 5 games
= 177 + 128 + 101 + 112 + 141
= 659
Average score of first 5 games
= 659 ÷ 5
= 131.8
(b)
Average score of 6 games
= 131.8 + 2.7
= 134.5
Total score of 6 games
= 6 x 134.5
= 807
Score of Julian's sixth game
= 807 - 659
= 148
Answer(s): (a) 131.8; (b) 148
