well what does C=? 70%? 83%? 75%
if a C is 70% of a grade then 70% of 75 is the lowest C possible
.7%2A75=52.5so if C=70% then u would need to answer 53 questions correctly.

Depends. What are the grading criteria? What percentage of correct answers represents a C?

Let x = how many questions you need to get right for a grade of c
By grade c, I assume this means 70% in your class.
x/75 = 0.70
After solving for x, I got 52.5 questions.
Rounding it off to the unit's place and it is about 53 questions.
