Challenge 85

Saint Anthony miracle worker

Difficulty level:

Manoel had a certain amount of money and found it too small. As he always complained about life, one day he found St. Anthony and made a proposal:

- Oh dear Saint Anthony, double the money I have, and I'll give you $ 10.00.

So the saint did. The other day, as he thought he still had little money, he made the same proposal to the saint, and the saint made the arrangement again, doubling the amount of money he had and getting $ 10.00.

On the third day, once again Manoel made the same proposal, but something unexpected happened. By the time the amount of money was doubled and he handed the saint $ 10, the money was over and he was left with nothing.

How much money did Manoel have on day one?
