You are missing a price on (2). Regardless, this should be B
You have:
Min3 < Bed3 < Min3 + 200
Min4 < Bed4 < Min3 + 600
Trying to find:
Min3 + 600 - Min4 = ?
(1) Min4 = 800
Given this, you can't find what you are looking for. Just imagine Min3 being a variable, INSUFFICIENT.
(2) Min3 + 200 - Min4 = Some Number
Min3 - Min4 = Some Number - 200
Plug this in:
600 + (Min3 - Min4) should get you the number
SUFFICIENT
