calculating percentages
How do I figure the percentage between 522 and 549? I know the difference is 27, but what is the percentage between 522 and 549? In other words, if I made 522 dollars one week, then 549 the next week, what is the percentage difference, or increase I guess, that I made?
Thanks.

calculate the difference:
$\displaystyle 549522=27$
divide by original value:
$\displaystyle \frac{27}{522}=5.17(10)^{2}$
multiply by 100.
$\displaystyle 5.17(10)^{2}(100)=5.17
$
5.17%

Thanks
Thank you for the answer.
