I have a question about I’m going backpacking in the north and I don’t know how much money to bring

Hello! i’m from chile and i have a question, I already have the hotels paid (with breakfast included) and my flights booked. The issue is that I don’t know how much money to withdraw from my savings account.

Considering that I’ll be doing this route with a friend in backpacking mode — hopefully taking intercity buses and avoiding Uber as much as possible (but we would use it if necessary) — and that we plan to cook most of our meals and only rarely eat out (I’m 20 years old and a student, so I don’t have much money), we’ll be traveling for 11 days through parts of Maceió, Maragogi, Porto de Galinhas, João Pessoa, Pipa, and Natal. We just want to explore and have a good experience.

Given all this, how much money would be reasonable to bring? Would 3,034.24 BRL be enough, or is that too little? i’m looking for recommendations, thanks
