C Correct answer
Explanation

First, simplify the square roots: √728.97 ≈ √729 = 27, and √89998 ≈ √90000 = 300. Calculate the right side: 297.08 + 27 - 300 = 24.08. For the left side: 34.03% of 550.08 ≈ 34/100 × 550 = 187. So we have 187/? ≈ 24. Solving: ? ≈ 187/24 ≈ 7.8, which rounds to 8. Option C (8) is the correct approximate value.
