A student's final grade in a course is determined by three components with different weights: Homework (20%), Midterm (30%), and Final Exam (50%). If a student scored 80 on Homework, 75 on the Midterm, and 80 on the Final Exam, what is their final course grade?
✓ Correct Answer: Option B
The final grade is a weighted average: (0.20 * 80) + (0.30 * 75) + (0.50 * 80) = 16 + 22.5 + 40 = 78.5.
