Explanation

Calculate each part: 16.78% of 1667 ≈ 0.1678 × 1667 ≈ 279.7 (approximately 280). For the division: 31.013 ÷ 9.97 ≈ 31 ÷ 10 ≈ 3.1. So the expression becomes 280 - 3.1 ≈ 276.9. The closest option is 275. The approximation slightly overestimates the first term, making 275 the better choice than 280.
