We have to find the GPA score for Jerry.

We have in the table the course grades and the course units.

We will transform the grades into a numeric scale first and then calculate a weighted average.

Finally, we will convert this average into its corresponding letter.

We can transform the grades into numeric values as:

• English: A --> 4.00

,

• Anthropology: A --> 4.00

,

• Chemistry: B+ --> 3.33

,

• French: C --> 2.00

,

• Theatre: B- --> 2.67

Now we can calculate a weighted average using the course units as:


\begin{gathered} G=(3\cdot4.00+3\cdot4.00+4\cdot3.33+3\cdot2.00+2\cdot2.67)/(3+3+4+3+2) \\ G=(12+12+13.32+6+5.34)/(15) \\ G=(48.66)/(15) \\ G\approx3.24 \end{gathered}

His average GPA is 3.24, which correspond to a B+.
