One gallon is my guess. Because if he adds 0.5 it will be too lite. If he adds 2 gallons it will be to strong. Because 100% lemon juice is sour. So yeah. Tell me if I am right.

yeah that was my guess. I would assume its 1.5 but that's not an option... I know there's a proper way to work this but I just can't remember lol

seems like an odd question, because you don't know how much juice you are starting with
if you start with 7 gallons, then you can't add anything
