1. The problem is to calculate the final grade based on weighted components. 2. The weights and achieved percentages are: - Reading Quizzes: 10% weight, 97% achieved - Concept Quizzes: 10% weight, 88% achieved - Homework: 15% weight, 98.45% achieved - Tests: 50% weight, 41.67% achieved - Final Exam: 15% weight, 77.14% achieved 3. The formula for weighted average grade is: $$\text{Final Grade} = \sum (\text{Weight}_i \times \text{Score}_i)$$ where weights are in decimal form. 4. Convert weights to decimals and multiply by scores: - Reading Quizzes: $0.10 \times 97 = 9.7$ - Concept Quizzes: $0.10 \times 88 = 8.8$ - Homework: $0.15 \times 98.45 = 14.7675$ - Tests: $0.50 \times 41.67 = 20.835$ - Final Exam: $0.15 \times 77.14 = 11.571$ 5. Sum all weighted scores: $$9.7 + 8.8 + 14.7675 + 20.835 + 11.571 = 65.6735$$ 6. Therefore, the final grade is approximately $65.67$%.
