A student's final grade is based on three exams: Exam 1 (25%), Exam 2 (35%), and Exam 3 (40%). If the student scored 80 on Exam 1, 70 on Exam 2, and 90 on Exam 3, what is the student's final grade?
✓ Correct Answer: Option C
The final grade is a weighted average: (0.25 * 80) + (0.35 * 70) + (0.40 * 90) = 20 + 24.5 + 36 = 80.5.
