1. Weighted Exam Score:
* You have a 70% weight on exams. Let's assume the 85 and 75 are your two exam scores.
* Average exam score: (85 + 75) / 2 = 80
* Weighted exam score: 80 * 0.70 = 56
2. Weighted Lab Report Score:
* You have a 20% weight on lab reports. We need the average lab report score to proceed. Let's call the average score on your lab reports 'x'.
* Weighted lab report score: x * 0.20 = 0.20x
3. Weighted Homework Score:
* You have a 10% weight on homework. Your homework score is 96.
* Weighted homework score: 96 * 0.10 = 9.6
4. Overall Average:
* Your overall average is the sum of the weighted scores: 56 + 0.20x + 9.6
* We need your average lab report score (x) to complete the calculation. Once you provide that, substitute it into the equation above. For example, if your average lab report score was 88:
56 + (0.20 * 88) + 9.6 = 56 + 17.6 + 9.6 = 83.2
Therefore, your overall average grade would be 83.2% if your average lab report score is 88%. You need to provide your average lab report score to get the final answer.
