Question

The mean bowling score for Mr. Kass's last 10 days was 155. If the sum of his bowling score for the last nine games was 1,300, what was his score on game 10?

Answer 1

To find Mr. Kass's score on game 10, multiply the mean score by the number of games to get the total sum and then subtract the sum of the last nine games from it. The score for game 10 was 250.

Step-by-step explanation:

To find Mr. Kass's score on the game 10, we can use the information about the mean score of his last 10 games along with the sum of his scores for the last nine games.

The mean score is the total sum of scores divided by the number of games. If his mean score over the last 10 games is 155, then the total sum of his scores over those 10 games would be 155 multiplied by 10, which equals 1,550. According to the question, the sum of his scores for the last nine games is 1,300. To find the score of the game 10, we subtract the nine-game total from the ten-game total.

1,550 (total of 10 games) - 1,300 (total of 9 games) = 250

Therefore, Mr. Kass's score on game 10 was 250.
