Answer:
$1,800,000
Step-by-step explanation:
The computation of the net working capital is shown below:
Net working capital = Current assets - current liabilities
where,
Current assets = Cash and marketable securities + Accounts receivable + Inventory
= $400,000 + $1,200,000 + $2,100,000
= $3,700,000
And, the current liabilities = accrued wages and taxes + Account payable + notes payable
= $500,000 + $800,000 + $600,000
= $1,900,000
So, the net working capital is
= $3,700,000 - $1,900,000
= $1,800,000
