Answer:
3. $2,123,612
Step-by-step explanation:
As we know that
Net working capital = Current assets - current liabilities
where,
Current assets = Cash and marketable securities + inventory + accounts receivables + other current assets
= $335,485 + $1,651,599 + $1,488,121 + $121,427
= $3,596,632
Current liabilities = Accounts payable + short-term notes payable
= $1,159,357 + $313,663
= $1,473,020
So, the net working capital is $2,123,612
