Answer 1

$57,500

Explanation:

There is 100% in the full amount, as always. If she has lost 4%, it stands to reason that she's got ( `100-4=` ) 96% left.
If we split the 96% in lumps of 1% (by dividing by 96), we can then multiply it by 100 to get the full (100%) original value:

`(96%)/96*100 = 100%`

`55200/96*100 = 57500 = $57,500`
