Answer:
Number of points need = 6 points
Step-by-step explanation:
Given:
New average = 5
Points peter has = 44
Total quiz play = 9
Find:
Points required for average of 5
Computation:
Total number of match = 9 + 1
Total number of match = 10
Average points = 5
Assume;
Number of points need = x
So,
Average points = [Total points] / Total number of match
5 = [44+x] / 10
50 = 44 + x
x = 6
Number of points need = 6 points
