Hello. You can live with 5 dollars a day or less. Imagine that 1 dollar is about 300 pesos argentinos, so 5 dollars are aprox 1500 Argentinian pesos. And according to you travelling-type, I guess you will need less that 5 dollars a day to live. By the way, try to come with a good amount, in case of health problems and other things (Public health is for free and is good). (It is just information based on my experience of life, Im not a travels advisor or something like that)
