Answer :

If 40% or .4 of her savings is $85 then we can write the equation .4s=$85 (s being the original amount in savings)
Divide both sides by .4 to get s= $212.50 as the original amount that she had
eah
$85 is 40% of her savings.

So, 

40% of x is egual to $85
40/100x = 85
0,4x = 85
x = 85 / 0,4
x = 212,5

[tex]ANSWER = \$ 212,50[/tex]
