Final answer:
School A's spending exceeds School B's spending by approximately $4,000 per student.
Step-by-step explanation:
To find how much School A's spending exceeds School B's spending, we need to subtract the amount spent per student by School B from the amount spent per student by School A.
So, $8,000 - $4,000 = $4,000
Therefore, School A's spending exceeds School B's spending by approximately $4,000 per student.
