Answer:
Total change to Akiko's score = 235 points
Explanations:
The number of targets missed by Akiko = 5
Number of points lost for each of the targets = 20
Total number of points lost for the 5 targets = 20 x 5
Total number of points lost for the 5 targets = 100 points
The total number of points used for penalization = 135 points.
Total change to Akiko's score = 100 + 135
Total change to Akiko's score = 235 points
