Kate has $37, Mary has $48, and Amy has $74.

Equations

Given that Mary, Kate and Amy have a total of $159, and Mary has $11 more than Kate, while Amy has twice as much money as Kate, to determine how much money each girl has, the following calculation must be performed:

M = K + 11
A = 2K
K = K
K + 11 + 2K + K = 159
4K = 159 - 11
K = 148 / 4
K = 37

So Kate has $37, Mary has $48, and Amy has $74.
