Answer:
Creed would need to score 27 points in the next game to have an average of 20 points per game.
Explanation:
The formula for average is:
Average = Total sum of values / Number of values
In this case, Creed has played three games and scored 24, 12, and 17 points. So the total sum of his points so far is 24 + 12 + 17 = 53.
Now, let's set up the equation to find the average:
20 = 53 + x / 4
We divide the total sum of points so far (53) by the number of games played (3) and add the unknown value of the next game's score (x) to the equation. Since we want an average of 20 points per game, we divide the total by the total number of games played so far (3) and add the unknown value of the next game's score (x) to the equation.
Now, we solve for x:
20 * 4 = 53 + x
80 = 53 + x
To isolate x, we subtract 53 from both sides of the equation:
80 - 53 = x
27 = x
