at first because of the context, I read it as ¢0.80 cents per word, but my brain got all tripped up over the dollar sign. I then started thinking about looking for a way to apply for that job. For $0.80 cents per word, I could wax poetically for pages upon pages of nonsense. I could even make it more beneficial for me by never using more than 2 syllable words. Using 3+ syllable words would start costing me money.
Write $5, not $5 dollars. The dollar sign denotes the unit, there is no reason to add the word after. Alternatively you could just write "5 dollars", there is no need for the dollar sign when you write "dollars" right after.
That way you dont have to worry about keeping your redundant units in sync.
