Suppose that the managers of the router division of Cisco Systems are considering the development of a wireless home networking$$appliance$,$ called HomeNet$,$ that will provide both the hardware and the software necessary to run an entire home from any Internet connection. Cisco$\text{'}$s receivables are $15\mathrm{.}3\%$ of sales and its payables are $14\mathrm{.}2\%$ of COGS. Forecast the required investment in net working capital for HomeNet assuming that sales and cost of goods sold$($COGS$)$ will be as$$follows:

Calculate the required investment in net working capital for year $0,$ year $1,$ year $2,$ year $3,$ and year $4.$
