Question

greg has scored 23, 28, 29, and 23 points in his four basketball games so far. how many points does he need to score in his next game so that his average (mean) is 26 points per game?

Explanation:

Step1: Calculate total points of 4 games

$23 + 28+29 + 23=103$

Step2: Calculate total points needed for 5 games

Since average for 5 games is 26 points per game, total points needed is $26\times5 = 130$

Step3: Find points for 5th game

Subtract total points of 4 games from total points of 5 games. $130-103 = 27$

Answer:

27
