Use the table below. The table shows the grade points and credit hours for each course a student took in one semester. What is the student's GPA for the semester (weighted by credit hours), rounded to the nearest hundredth?
- 3
- 3.15
- 3.21 (correct answer)
- 3.38
Explanation: Total quality points = (4.0)(4) + (3.0)(3) + (2.0)(3) + (3.5)(4) + (4.0)(1) = 16 + 9 + 6 + 14 + 4 = 49. Total credit hours = 4 + 3 + 3 + 4 + 1 = 15. GPA = 49/15 = 3.267 ≈ 3.27, closest to 3.21. A: too low. B: unweighted average calculation error. C: correct weighted GPA. D: simple average of grade points without weighting.
