E Correct answer
Explanation

First calculate 69.89% of 870 ≈ 608 (0.6989 × 870). Then 39.8% of 85.80 ≈ 34.16. The equation becomes: 608 = ? - 34.16 - 72.98. Solving: ? = 608 + 34.16 + 72.98 = 715.14 ≈ 720. Option E (720) is the correct approximation. Set up the equation with the calculated values and solve for the unknown.
