C Correct answer
Explanation

0.4 * 620 = 248. 0.35 * 4500 = 1575. 324^2 / 18 = 104976 / 18 = 5832. 248 + 1575 + ? = 5832. ? = 5832 - 1823 = 4009.

AI explanation

Using approximation, the expression becomes 40 percent of 620 plus 35 percent of 4500 plus question mark equals 324 squared divided by 18. This simplifies to 248 plus 1575 plus question mark equals 5832, meaning 1823 plus question mark equals 5832. Subtracting 1823 from 5832 gives 4009.
