Answer:
($230)
Step-by-step explanation:
Net working capital = Current assets - Current liabilities
2017 Net working capital
= $3,175 - $1,645
= $1,530
2018 Net working capital
= $2,920 - $1,620
= $1,300
Change in net working capital
= $1,300 - $1,530
= -$230
Therefore the company's 2018 change in net working capital is ($230).
