which is correct?
a couple billions of dollar
a couple billion of dollars
"two billion dollars" would work just fine and is less iffy.
a couple = 2
a few = 3 to 5
several = 5 or more
And when you use "a couple" in a sentence like this, you need to add the word "of" after it: e.g., I have a couple of CDs I'd like to get rid of.
then would "it cost them billions of dollars" work?
i just don't know is the -s on billion or dollar.
Yes, you could say any of these:
It cost them billions of dollars. (Make sure it's clear what "it" is.)
It cost them two billion dollars.
It cost them a couple of billion dollars. (This is not as formal as the other two, however.)
What is your choice?
