Hello,
It's all written in diagram 1:
Best,

Hello!
What the case says > Looking back at the diagram 1 shows that out of the total revenue of $400 million about $20 million will be lost.
What it means > 400 million is the sum of revenues from all patients referred, and 20 (i.e.,10 x 2) corresponds to those doctor referring 9 or 10 patients.
Hope it helps!
Cheers,

Make sure you look at the exhibit!
If you add the revenue from patient # (patients 1 through 10), you'll get $400m.
Doctors that have more than 8 patients (i.e. 9, 10) represent $10m in revenue each, which totals $20m
