There are 8 more students 55 inches tall or less than students that are more than 55 inches.
Work:Add all of the circles together for 53.5,54,54.5,and 55.
That comes out to 15 circles/students.
Then add all of the circles together for 55.5,56,and 56.5
That comes out to 7 circles/students.
Lastly subtract 15-7 and u get 8.
