Answer:she needs to score 27 points

Explanation:

Susan has scored 11 18 27 25 and 30 points in her five basketball games so far. Therefore, the total points scored for the 5 games would be

11 + 18 + 27 + 25 + 30 = 111

Average points scored = 111/5 = 22.2

Let x represent the number of points that she needs to score in her next game so that her average is 23 points per game. Therefore

(111 + x)/6= 23

Cross multiplying by 6, it becomes

111 + x = 23 × 6 = 138

x = 138 - 111 = 27
