i need help with another math question?

Question

Here is my other question im have problems with i dont exactly understand how to do this one:

In a college, some courses contribute more towards an overall GPA than other courses. For example, a science class is worth 4 points; mathematics is worth 3 points; History is worth 2 points; and English is worth 3 points. The values of the grade letters are as follows, A= 4, B=3, C=2, D=1, F=0. What is the GPA of a student who made a “C” in Trigonometry, a “B” in American History, an “A” in Botany, and a “B” in Microbiology?


2.59
2.86
3.08
3.33
3.67


i know i need to add the 4+3+3+2 but i dont know what i need to do from there can u please help and walk me through the best you can thanks

ok i noticed you got 4+4+3+2 were did the 4 come from i only see 3+3+4+2 ? can u explain that to me please

ok nevermind i pulled my head out and seen what i was doing wrong 4+4+3+2

Answer 1

It's weighted, it isn't a straight adding and dividing by 4...

You need to multiply each number by the weighting of the course.
Trig: C (2.0) x 3 pts = 6
Hist: B (3.0) x 2 pts = 6
Botany: A (4.0) x 4 pts = 16
Microbiology: B (3.0) x 4 pts = 12

Grade points:
6 + 6 + 16 + 12 = 40 pts

Course points (these are the weights for 1 math, 1 history and 2 science courses):
3 + 2 + 4 + 4 = 13 pts

Dividing: 40 / 13 ≈ 3.077

So the student has a little more than a B average.

Answer 2

Multiply the points by the class score divide by the total points.
