Andronicus Corporation $($AC$)$ has the following jumbled information about an investment proposal:

Revenues in each of years $14=$ $$37,000$

Year $0$ initial investment $=$ $$57,000$

Inventory level $=$ $$18,500$ in year $1,$ $$20,700$ in year $2,$ and $$13,500$ in year $3$

Production costs $=$ $$12,100$ in each of years $14$

Salvage value $=$ $$13,700$ in year $4$

Depreciation $=100\%$ immediate bonus depreciation

Tax rate $=21\%$

There is an additional $6-$month lag for all cash flows after year $0.$ For example, customers pay consistently with a $6-$month lag, as AC does for production costs, taxes, etc.
