The average number of points you scored in the first 9 basketball games of the season was 23. what do you need in the 10th game to get your average to n? oa. n-23 ob, 10n-207 o c. 9n-23 d. 207-9n

B. 10n-207

Step-by-step explanation:

Given,

The average number of points of 9 games = 23,

∵ Sum of observations = their average × number of observations

So, the total points for 9 games = 9 × 23 = 207,

Now, if the average of 10 games is n,

Then the total points for 10 games = 10n,

Hence, the number of points earned in 10th game = the total points for 10 games - the total points for 9 games

= 10n - 207

i.e. OPTION B is correct.
