Final answer:
To find by how many points Goofy's score was greater, subtract Joey's and Color's scores from Goofy's highest score.
Step-by-step explanation:
In order to find by how many points Goofy's score was greater, we need to subtract Joey's and Color's scores from Goofy's highest score.
Goofy's highest score was 9.7, so we subtract 9.7 from 9.8 (Joey's score) and 9.5 (Color's score).
The difference between Goofy's score and Joey's score is 9.8 - 9.7 = 0.1 points.
The difference between Goofy's score and Color's score is 9.7 - 9.5 = 0.2 points.
