Answer:
net working capital decreased by $2,250 during the year
Explanation:
net working capital = current assets - current liabilities
current assets: -$1,200 (cash) + $200 (accounts receivable) - $150 (inventory) = net change of -$850
current liabilities: +$1,400 (current liabilities) = net change of +$1,400
net change in working capital = -$850 - $1,400 = -$2,250
fixed assets are not included in this calculation
