Compute the grade point average (GPA)

[rainbow1]

a student earned grades of A, C, A, A, and B. Those courses had these corresponding numbers. of credit hours:1,6,3,1,3. The grading system assigns quality points to letter grades as follows: A=4, B=3, C=2, D=1, and F=0. Compute the grade point average (GPA) and round the result to two decimal places

Hello, and welcome to MHB! (Wave)

What you want to use here is a weighted average:

$$\text{GPA}=\frac{1(4)+6(2)+3(4)+1(4)+3(3)}{1+6+3+1+3}=\frac{41}{14}\approx2.93$$

Does that make sense?
