Atlanta is rapidly turning into a multicultural city like New York City. The city is pretty diverse, but the cheaper cost of living is bringing even more people here. English is the main language of course, but here and there you will find people speaking Spanish, Amharic (the official language of Ethiopia) and Hindi (a language spoken in India). We have very large Ethiopian and Indian communities in Atlanta.
The USD (United States Dollar) is used here, of course! In Argentina, I think that the currency is called the Argentine Peso. We'll talk more about it when I get to Argentina.
Atlanta is huge, so it's hard to say how much a bottle of water costs in the entire city, as it also depends on what brand of water you're buying. If you want the fancy spring water, that will cost you about $3.50. If you just want a regular bottle of water, you can get that for about $1.75 or less. Hopefully, it'll be cheaper in Argentina.
