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:
[tex]\begin{gathered} G=\frac{3\cdot4.00+3\cdot4.00+4\cdot3.33+3\cdot2.00+2\cdot2.67}{3+3+4+3+2} \\ G=\frac{12+12+13.32+6+5.34}{15} \\ G=\frac{48.66}{15} \\ G\approx3.24 \end{gathered}[/tex]
His average GPA is 3.24, which correspond to a B+.
