1. The problem asks for the weighted mean GPA for Mia's summer classes using the 4-point grading system where A=4, B=3, C=2, D=1. 2. List the given data with grades converted to points: - Art: A = 4 points, 1 unit - Biology: B = 3 points, 3 units - Geography: C = 2 points, 2 units - Health: B = 3 points, 3 units - Music: A = 4 points, 2 units 3. Multiply each grade point by the corresponding course unit to find weighted points: - Art: $4 \times 1 = 4$ - Biology: $3 \times 3 = 9$ - Geography: $2 \times 2 = 4$ - Health: $3 \times 3 = 9$ - Music: $4 \times 2 = 8$ 4. Sum all weighted points: $$4 + 9 + 4 + 9 + 8 = 34$$ 5. Sum all course units: $$1 + 3 + 2 + 3 + 2 = 11$$ 6. Calculate the weighted mean GPA by dividing total weighted points by total units: $$\frac{34}{11} \approx 3.09$$ 7. Among the answer choices, the closest value is 3.3. **Final answer:** $3.3$
