grade percentage

Question

In Victoria's Mythology class Quizzes are worth 15% of the final grade, Exams are worth 55%, Projects are worth 25%, and Attendance is worth 5%.

At mid-semester Victoria scored 117 out of 150 points on quizzes, 78, 87, and 90 on the first three exams,each worth 100 points. She got extra credit on her project with a score of 28 out of 25 possible points, and she had perfect attendance to class. Compute Victoria's grade percentage in the class so far. 

Answer 1

Q = 15

E = 55

P=25

A = 5

Q = 117/150 x 15 = 117/10 = 11.7 points

E = (78+87+90/)3/100 = 85/100 = .85 x 55 = 46.8 points

P = 28/25 x 25 = 28 points

A = 1 x 5 = 5 points

Total points = 11.7 + 46.8 + 28 + 5 = 91.5 = final grade = A or A - So far
