A retailer is looking to expand operations at all of their stores for an initial investment of $$840.$ This investment will be depreciated on a straight line basis over the project's $10$ year life. The expansion is expected to produce annual cash inflows of $$610$ in consecutive years over the life of the project beginning one year from today, while also producing annual cash outflows of $$360$ in consecutive years over the life of the project, also beginning one year from today. What is the project's NPV if the corporate tax rate is $34\%$ and the project's required rate of return is $14\%?$
