What is the correct form of this sentance, if this isn't already correct? ...
"..services at $0.80 per word, or $100 - whichever is greater."
It looked right to begin with, but then I toyed with;
"..services at $0.80 per word, or $100, whichever is greater."
and..
"..services at $0.80 per word or $100, whichever is greater."
.. But can't figure out which (if any) are correct.
