How can I calculate the Total Owner's Equity as of 12/31/05 if:
 - Company begins business on 1/1/05
 - Person A contributes $100,000 in equipment and cash
 - Peson B earns $200,000 of revenue and incurs $100,000 of expenses,
but no liabilities.

OK but doesn't Person B contribute anything at the starting of the
year/business? I mean is Person A just a silent partner and Pesron B
contributes through his income??? Person A has owner's equity of
$100,000 for sure through out as there is no chnage or variation of
his part. Person B however, seems to be contributing no eqity (shares,
equipment, cash, property, vehicles etc) at the start. You cannot
count his income as his equity.
