this is a problem in my statistics class, and I am lost to me, it is confusing or missing something here is the problem please help

grade points are assignede as follows: a=4,b=3,c=2,d=1,f=0. grades are weighted according to credit hours. if a student receives an A in a four-unit class, a d in a two-unit class, a b in a three-unit class and a C in a three-unit class, what is the students grade point average

To find the student's grade point average (GPA), we need to calculate the total grade points earned and divide it by the total credit hours taken.

Let's assign the following values:
A = 4 (grade points for an A)
B = 3 (grade points for a B)
C = 2 (grade points for a C)
D = 1 (grade points for a D)
F = 0 (grade points for an F)

Given:
- A in a 4-unit class.
- D in a 2-unit class.
- B in a 3-unit class.
- C in a 3-unit class.

Now, let's calculate the total grade points earned:
Total grade points = (Grade points for class 1) + (Grade points for class 2) + (Grade points for class 3) + (Grade points for class 4)

Class 1: A in a 4-unit class
Grade points for class 1 = A * credit hours = 4 * 4 = 16

Class 2: D in a 2-unit class
Grade points for class 2 = D * credit hours = 1 * 2 = 2

Class 3: B in a 3-unit class
Grade points for class 3 = B * credit hours = 3 * 3 = 9

Class 4: C in a 3-unit class
Grade points for class 4 = C * credit hours = 2 * 3 = 6

Total grade points earned = 16 + 2 + 9 + 6 = 33

Next, let's calculate the total credit hours taken:
Total credit hours = Credit hours for class 1 + Credit hours for class 2 + Credit hours for class 3 + Credit hours for class 4

Credit hours for class 1 = 4 units
Credit hours for class 2 = 2 units
Credit hours for class 3 = 3 units
Credit hours for class 4 = 3 units

Total credit hours = 4 + 2 + 3 + 3 = 12

Finally, let's calculate the GPA:
GPA = Total grade points earned / Total credit hours taken
GPA = 33 / 12

The student's grade point average is 2.75.

Note: Since the problem does not provide specific information about the grading scale or any potential changes to the scale, we assume the standard grading scale where A=4, B=3, C=2, D=1, and F=0.

To calculate the student's grade point average (GPA), we need to multiply each grade by its corresponding credit hours and then divide the total sum by the total number of credit hours.

In this problem, the student received:
- An A in a four-unit class (worth 4 credit hours)
- A D in a two-unit class (worth 2 credit hours)
- A B in a three-unit class (worth 3 credit hours)
- A C in a three-unit class (worth 3 credit hours)

To calculate the weighted grade point average, we need to assign a numerical value to each grade:

- A: 4
- B: 3
- C: 2
- D: 1
- F: 0

Now let's calculate the GPA step by step:

1. Multiply the grade by the credit hours for each class:
- A (4) in a four-unit class: 4 * 4 = 16
- D (1) in a two-unit class: 1 * 2 = 2
- B (3) in a three-unit class: 3 * 3 = 9
- C (2) in a three-unit class: 2 * 3 = 6

2. Sum the results:
16 + 2 + 9 + 6 = 33

3. Calculate the total credit hours:
4 + 2 + 3 + 3 = 12

4. Divide the sum of the grades (33) by the total credit hours (12):
33 / 12 = 2.75

Therefore, the student's grade point average (GPA) is 2.75.
