A student is given this formula to calculate their grade for the term

Course Grade is determined as follows:
Course Grade = 0.30(Quiz Avg) + 0.10(Participation) + 0.15(Exam 1) + 0.15(Exam 2) + 0.30(Final Exam
.30(Quiz Average) + .10 ( Participation) + .15 (Exam 1) + .15 (Exam 2) + .30 ( Final exam) equals the final grade.
Given this information what is the expected grade?
Quiz Average=84
Participation=120
Exam 1=50
Exam 2=90

G=0.30*Q + 0.10*P + 0.15*E1 + 0.15*E2+ 0.30*F
Substitute for the given values,
G=0.30*Q + 0.10*P + 0.15*E1 + 0.15*E2+ 0.30*F
G=0.30*(84) + 0.10*(120) + 0.15*(50) + 0.15*(90)+ 0.30*(30)
G=25.2 + 12 + 7.5 + 13.5 + 9
G=67.2
The student got a 67.2, that's probably an F or maybe a D-.
