bobpursley,
You have to assign a value to A,B,C,D. Since I don't know the grading scheme you have, I will make up one:
A=4.0
B=3.0
C=2.0
D=1.0
F=0
avg grade=sum of values*percent
= 1.0*.049+2.0*.147+3.0*.292+4.0*.512
I get 3.27

Damon,
Assign numbers to grades like 1 = D and 2 = C and 3 = B and 4 = A
The sum of all the grades divided by the number of students.
[ 2*1 + 6*2 + 12*3 + 21*5 ] / [2+6+12+21]

mary,
A student's grade in a course is the average of 4 test grades and a final exam that is worth twice as much as each test. Suppose a student has test grades of 89, 88, 83, and 94. Write an equation to model this situation where xis the student's grade on the final exam and yis the student's average for the course.
