Kate has $37, Mary has $48, and Amy has $74.
<h3><u>Equations</u></h3>
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.
