The error comes about by being in how you account for where the $ in change went after the purchase of the shoes,
first you used the $ in change to give to your friend $ and from remaining $ you erroneously subtract $ from what you owe each of your mom and sister ($ - $ = $) (you're counting backwards!) and then you to that total debt balance of $ ($ you owe mom + $ you owe sister) and the ${{3}}} which you gave to your friend then arrive at the false sum of $, when you should have correctly and added the $ change back onto the $-cost of the shoes so that the correct total balance of $ would then be realized and accounted for as follows:

BEFORE THE PURCHASE OF THE SHOES
Amount borrowed from mom -- $
Amount borrowed from sister -- $
Total borrowed -- $

-------------------------------------------------------------------------

AFTER THE PURCHASE OF THE SHOES
Cost of shoes -- $
plus $ change:
three dollars to friend -- $
One dollar to mom -- $
One dollar to sister -- $
Total $

or simply, you add $
