Suppose that the managers of the router division of Cisco Systems are considering the development of a wireless home networking$$appliance$,$ called HomeNet$,$ that will provide both the hardware and the software necessary to run an entire home from any Internet connection. Cisco$\text{'}$s receivables are $15\mathrm{.}8\%$ of sales and its payables are $14\mathrm{.}8\%$ of COGS. Forecast the required investment in net working capital for HomeNet assuming that sales and cost of goods sold$($COGS$)$ will be as$$follows:

Year $01234$

Sales $($$$)23,355$x $26,557$x $23,915$x $8,617$x

COGS $($$$)9,595$x $10,769$x $9,690$x $3,463$x

The required investment in net working capital for year $0$ is $$$$\_\_($Round to the nearest integer. Enter decreases as negative$$numbers$.)$
