Which meaning?

[Lie.K.]

Hello :)

I'd like to ask about the expression at shopping.
Would you take a look at the following sentence?

#1 That comes to 5 dollars with tax.
How much should I pay if a salesclerk says this? 5 dollars or 5 dollars plus tax?
I don't understand " with " well here. Does "with" mean "include" or "plus"?

Thank you.

It would normally mean 'including'. (If in doubt, however, I would suggest that you double-check: "is that including, or excluding, tax?")
