A 27+18+24+32+15+277+s=25
Start Fraction 27 plus 18 plus 24 plus 32 plus 15 plus 27 over 7 End Fraction plus s equals 25

B 27+18+24+32+15+27+s7=25
Start Fraction 27 plus 18 plus 24 plus 32 plus 15 plus 27 plus s over 7 End Fraction equals 25

C 27+18+24+32+15+17+s7=25
Start Fraction 27 plus 18 plus 24 plus 32 plus 15 plus 17 plus s over 7 End Fraction equals 25

D 143s7=25

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.

  1. Calculate the total points scored in the first 6 games: 27 + 18 + 24 + 32 + 15 + 27 = 143

  2. 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.
