To find the score for the last game that will give Carlos an average of 25 points per game, we need to first calculate the total points scored in the first 6 games and then set up the equation for the average.
-
Calculate the total points scored in the first 6 games: 27 + 18 + 24 + 32 + 15 + 27 = 143
-
We want the average over 7 games to be 25 points, so the total points after 7 games must be: Average = Total Points / Number of Games 25 = (143 + s) / 7
Now we can rewrite this equation in a way that is listed among your options:
-
Multiply both sides by 7: 25 * 7 = 143 + s 175 = 143 + s
-
Subtract 143 from both sides: s = 175 - 143 s = 32
Now let's evaluate the options provided:
A: \( 27 + 18 + 24 + 32 + 15 + 27 + s = 25 \) B: \( \frac{27 + 18 + 24 + 32 + 15 + 27 + s}{7} = 25 \) C: \( \frac{27 + 18 + 24 + 32 + 15 + 17 + s}{7} = 25 \) D: \( \frac{143 + s}{7} = 25 \)
The correct equation is:
B: \( \frac{27 + 18 + 24 + 32 + 15 + 27 + s}{7} = 25 \)
or
D: \( \frac{143 + s}{7} = 25 \)
Both B and D set the correct form to find the score for the last game. However, since Option B details all points clearly, it's the most explicit.
