Credit courses

A student takes a 5 credit course, a four-credit course, two three-credit courses, and a one-credit course. He gets a C in the five-credit course, a B in the four-credit course and one of the three-credit courses, and an A in the other three-credit course and the one-credit course. On a GPA scale, C=2, B=3, and A=4. What is the student's GPA for this semester?

Final Answer:

m =  3

Step-by-step explanation:

$$\begin{gathered} A=4 \\ B=3 \\ C=2 \\ m=\frac{5\cdot C+4\cdot B+3\cdot B+(3-1)\cdot 2\cdot A+A\cdot 1}{5+4+3+2\cdot (3-1)+1}=\frac{5\cdot 2+4\cdot 3+3\cdot 3+(3-1)\cdot 2\cdot 4+4\cdot 1}{5+4+3+2\cdot (3-1)+1}=3 \end{gathered}$$
