Answer:
6 games
Explanation:
Before the last game, Jonas had 88 points
In the last game, Jonas scored 23 points
Total points scored in the season = points before last game + point on last game
Total points of the season = 88 + 23
Total points of the season = 111 Points
Further ahead, we're told Jonas had a season average of 18.5 points. This means that he scored an average of 18.5 points in all the games in played in the season, each. We're then required to find the number of games he played.
To find the number of games he played, we divide the total number of points he scored in a season by the average points he scored in a game. Something like this
Number of games played = total points scored / average points scored
Number of games played = 111 / 18.5
Number of games played = 6.
Therefore, Jonas played 6 games during the season
