Need help in solving this
To receive an A grade, a student must average 100 or less but more than 93. If Zane received an A in the course and had five grades of 95, 92, 98, 76, and 100 before taking the final exam, what were the possible grades for his final if there were 100 points possible? (Assume all six grades are weighted equally and let x represent the unknown score.)

Answers
mean = ∑x/n
93 = (95+92+98+76+100+x)/6
Solve for x. x ≥ ?
93 = (95+92+98+76+100+x)/6
Solve for x. x ≥ ?
