B Correct answer
Explanation

Equation: (7643 + x) / 4 = (502 * 6 * 12) / 6. (7643 + x) / 4 = 502 * 12 = 6024. 7643 + x = 24096. x = 24096 - 7643 = 16453.

AI explanation

Approximate the denominator 3.99 as 4 and simplify the right side to 502 multiplied by 6. Multiplying both sides by 4 gives 7643 plus the unknown equals 12048. Subtracting 7643 from 12048 yields an approximate value of 16405, which is closest to the required value.
