B Correct answer
Explanation

Calculate each percentage separately and add them: 17.1% of 725 = 0.171 × 725 ≈ 124.0, and 12.8% of 643 = 0.128 × 643 ≈ 82.3. Their sum is approximately 206.3, which rounds to 207. Option A (117) is too low, while C (272), D (180), and E (307) are either too high or don't match the approximation.
