Answer:
Day 1: you start with 1 penny but end with 2^1 pennies
Day 2: you start with 2 pennies and end with 2^1*2=2^2 pennies
Day 3: you start with 2^2 pennies and end with 2^2*2=2^3 pennies
...
Day 30: you start with 2^29 pennies but end with 2^29*2=2^30 pennies
In dollars, you now have $10,737,418.24.
(And not what everyone else is saying, $5,368,709.12, because 1 penny is what you have on day 0, not on day 1, when the doubling started)
Of course, if every day you are adding what you are getting to what you already had, then in the end you would have $(2^31-1)/100, or $21.474.836,47.
I also agree with Nathan and Andrew in the sense that the wording of the question might lead you to a completely different answer: $0.31.
(Oddly enough, Nathan counted the days right for this different answer but not for the other one!)
