__Method__
We created the equation y = 2 ^(x-1). We then plugged in the two possible numbers of days in a month (30 and 31).

__Solution__
y = 2^(30-1) = $5,368,709.12 y = 2^(31-1) = $10,737,418.24

__Explanation__
For a month with 30 days or less, at most you would get $5,368,709.12, so it would be better to take the $10 million lump sum. For a month with 31 days, you would get $10,737,418.24, so it would be better to take the penny a day doubling.
