Answer:
change in net working capital = $21,903
Explanation:
given data
beginning current assets = $121,306
beginning current liabilities = $124,509
end of the year current assets = $122,418
end of the year current liabilities = $103,718
solution
we get here working capital at beginning that is express as
working capital = Current assets - current liabilities   ......................1
put here value we get
working capital = $121,306 - $124,509 Â
working capital = -$3203 Â
and now we get here working capital for end of year that is
working capital = Current assets - current liabilities   ......................2
working capital = $122,418 - $103,718
working capital = Â $18,700
so now we can get change in net working capital that is difference between  beginning and ending working capital
change in net working capital = $18,700 Â - (-$3,203)
change in net working capital = $21,903
