How far does 100 USD go in Brazil?

I'm curious to know, how much purchasing power does 100 USD hold in Brazil? Considering the current exchange rates and the local cost of living, what kind of goods and services can one typically expect to acquire with such an amount? Is it a substantial amount that can cover a significant portion of daily expenses, or is it more of a small luxury to be enjoyed sparingly? I'm eager to understand the financial realities of spending in Brazil for someone with 100 USD in their pocket.
