With goldfish, yes.
Now, you said you have a 110 gallon tank. If you only put a couple of goldies in there to begin with, 25% will probably be adequate. After the tank cycles fully, you could add others, one at a time, and would probably need to up the quantity of the water changes.
I'm sure you've read how incredibly messy goldfish are. In addition to that, they have a significant body mass.
I'd also suggest that you may want to reconsider the live plant idea. Plants are a natural filtration system, something that is a definite plus for any tank, and most especially for a goldfish tank.
I don't know what type of goldfish you are considering, but if it's any of the delicate fancies (bubble eyes, celestials, etc.), look over any decorations carefully for sharp edges.
Doorways in caves and those double rock things with the holes in the middle look real cute, but fancy goldfish are kind of clumsy, and they don't understand that while they have grown, the opening in that decoration hasn't.
