Answer:
x≥17
Step-by-step explanation:
The next game will be game number 6. To get an average of 15 per game you have to have the total amount reached which is 15×6(90). To see how many points you are missing you have to subtract the total points from the first 5 games from 90, so 90- 73. The answer would be 17. so you would have to get 17 points to get an average of at least 15 points per game.
