Question

ivana has scored 14, 19, 23, 28, and 21 points in her five basketball games so far. how many points does she need to score in her next game so that her average (mean) is 21 points per game?

Explanation:

Step1: Calculate total points for 6 games

The average for 6 games is 21 points. So the total points for 6 games should be $21\times6 = 126$ points.

Step2: Calculate total points of first 5 games

The sum of points in the first 5 games is $14 + 19+23 + 28+21=105$ points.

Step3: Find points for 6th game

Subtract the total of first 5 - games from the total of 6 - games. So the points needed in the 6th game is $126−105 = 21$ points.

Answer:

21
