💡 Model Answer
To compute the average billing amount per department, join visits and billing, group by department, and use AVG. Example:
SELECT v.department,
AVG(b.amount) AS avg_billingFROM visits v
JOIN billing b ON v.visit_id = b.visit_id
GROUP BY v.department;
This gives the mean billing amount for each department.
