The main idea is adding ranges. Established patients vary from 16 to 20 per day, while new patients are a fixed 2 each day. So the smallest total is 16 + 2 = 18, and the largest total is 20 + 2 = 22. The daily total can be anywhere from 18 to 22, inclusive, so the range is 18-22. This is why other numbers (like just 18 or just 22) don’t capture the full daily variability, and 30 would imply a different combination.
