Well through deduction you can immediately tell she had $1,000 dollars in her savings. Due to how it's like saying she paid $55 dollars which is 55% of her money, how much did she have in total?
However to properly solve the problem:
55% can be seen as 0.55 in decimal form. So... divide $550 by 0.55 and you'll get your answer.
550 / 0.55 = 1,000
Therefore she had 1,000 dollars before spending.
I hope that helps, have a great rest of your day! ^ ^
