Answer:
   8 days
Step-by-step explanation:
On day 8, Isabella will save 256 nickels, bringing her total to 510.
_____
The number of nickels saved on day n is 2^n. The total is 2^(n+1)-2.
_____
The above can be written down from your knowledge of binary sequences. If you want a more formal development, read on.
__
The number of nickels saved on day n is a geometric sequence with first term 2 and common ratio 2. The n-th term of the sequence is ...
   an = a1·r^(n-1) = 2·2^(n-1) = 2^n
The sum of n terms of the sequence is ...
   S = a1(r^n -1)/(r -1) = 2(2^n -1)/(2-1)
   S = 2^(n+1) -2
__
We want S > 500, so ...
   500 < 2^(n+1) -2
   502 < 2^(n+1)
   251 < 2^n
   log(251) < n·log(2)
   n > log(251)/log(2)
   n > 7.97 . . . . . . . . 8 days or more to save more than 500 nickels
