Mr. Wilson's math answer question
It's based on the grading range.
for example, the letter grades would fall into these grade ranges:
A: 100% to 90%
B: 89% to 80%
C: 79% to 70%
D: 69% to 60%
F: 59% and lower.
Therefore, since the student got 11 out of 14 correct, their grade would be 78.5%. Which is a C grade.
