Answer:
9 days
Step-by-step explanation:
Given isabella saves a nickel a day.From this day onwards she kept on incresing the savings by doubling them.
Here it form's a geometric progression with first term(a) = 1 and common ratio (r) = 2
S(n) = ![a(\frac{r^{n}-1 }{r-1} )](https://tex.z-dn.net/?f=a%28%5Cfrac%7Br%5E%7Bn%7D-1%20%7D%7Br-1%7D%20%29)
Given condition is S(n) >500
![\frac{2^{n}-1 }{2-1}>500](https://tex.z-dn.net/?f=%5Cfrac%7B2%5E%7Bn%7D-1%20%7D%7B2-1%7D%3E500)
![2^{n}>501](https://tex.z-dn.net/?f=2%5E%7Bn%7D%3E501)
n ≥ 9
So it will take 9 days for her savings to be more than 500
