Let the amount each had initially be x.

x - 18 = 2*(x - 25) = 2x - 50

x = 32

Here is your bar model:

This is a unit bar: [xxx]

Before - the had equal amounts, then they each spent some money. In the end, Lily has twice as much as Sara, or 2 units.

Lily [xxx][xxx]<----$18---->|

Sara [xxx]<-----$25-------->|

If they started out the same, the second unit bar for Lily must be equal to $25 - $18, so $7

[xxx]=$7

Lily had 2 units (2 x $7)+$18 at first.

Sara had 1 unit ($7)+$25 at first.
