Question

maya kept track of the points she scored during her first five basketball games in the table shown.

game	points scored
2	12
3	10
4	6
5	14

after game 6, her mean number of points scored per game is 9.
how many points did maya score in game 6?

Explanation:

Step1: Calculate sum of first 5 - game scores

$8 + 12+10 + 6+14=50$

Step2: Calculate sum of scores after 6 games

The mean after 6 games is 9, and the number of games is 6. So the sum of scores after 6 games is $9\times6 = 54$

Step3: Find score of game 6

Let the score of game 6 be $x$. We know that the sum of the first 5 - game scores plus the score of game 6 equals the sum of scores after 6 games. So $x=54 - 50=4$
