We let x = Kim's amount
            y = Laura's amount
            z = Molly's amount

We have three unknowns and it should be that we have three equations to set up to be able to solve this.

x + y + z = 385    (1)
z - x = 105           (2)
2/5 = x/z              (3)

Solving simultaneously, we can get the values as follows:

x = 70
z = 175
y = 140

Therefore, the percentage that Laura got was 36.4% of the whole money. Hope this answers the question.
