urrent Attempt in Progress

Debra Shrills is considering an expansion of one of its existing buildings to add more manufacturing space for its kid$-$friendly noisemakers. Several possible scenarios exist for future cash flows, as follows.

Construction costs of $$499,000$; steady sales and costs each year, netting to an annual operating cash inflow of $$70,000$; the expansion would have no salvage value at the end of its $10-$year useful life $($the building would be repurposed for a different product$).$

Construction costs of $$499,000$; rising and then falling net cash flows each year for $10$ years, as follows: $$50,000$ for the first $2$ and last $2$ years, $$172,000$ for years $3-5,$ and $$101,000$ for years $6-8.$

Construction costs of $$698,000$; no cash flows in year $1,$$$74,000$ in years $2$ and $3,$$$152,000$ in year $4,$$$99,500$ in years $5-8,$ and $$51,000$ in the last $2$ years.
