Eastern Clothing Company is considering manufacturing a new style of shirt, whose data are shown below. The

equipment to be used would be depreciated by the straight$-$line method over its $3-$year life and would have a zero

salvage value, and no new working capital would be required. Revenues and other operating costs are expected

to be constant over the project's $3-$year life. However, this project would compete with other Eastern's products

and would reduce their pre$-$tax annual cash flows. What is the project's NPV$?($Determine if we need to add in tax shield as well? Explain why or why not$)$
