Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Approximate: 721.001 ≈ 720, 7.998 ≈ 8, so 720 × 8 = 5760. Then 6.05 ≈ 6, 8.010 ≈ 8, so 6 × 8 = 48. Total = 5760 + 48 = 5808, closest to 5800. Option B is correct. The slight overestimation in first product compensates for second product.
