Will's bowling average was 123 after 8 games.
Step-by-step explanation:
Given,
Average after 5 games = 120
We know that;
Average = [tex]\frac{Sum\ of\ scores}{No.\ of\ games}[/tex]
120 = [tex]\frac{Sum\ of\ scores}{5}[/tex]
Sum of scores in 5 games = 120*5 = 600
Scores for next three games = 118, 124, and 142
Average for 8 games = [tex]\frac{Sum\ of\ scores}{No.\ of\ games}[/tex]
Average for 8 games = [tex]\frac{600+118+124+142}{8} = \frac{984}{8}[/tex]
Average of 8 games = 123
Will's bowling average was 123 after 8 games.
