There are 204 students, 48 earned "C" so 48/204(100%)=23.5% earned "C"
A circle=360 degrees, (0.235)(360)=84.7 degrees.
ANSWER: The "C" grades sector would correspond to 85 degrees.
CHECK:
(360 degrees)(204 students)=1.765 degrees per student
(1.765 degrees per students)(48 students with "C")=84.7 degrees
