You have been hired as a consultant for Pristine Urban$-$Tech Zither, Inc. $($PUTZ$),$ manufacturers of fine zithers. An excerpt from the company's marketing report is as follows:

The zither industry will have a rapid expansion in the next four years. With the brand name recognition that PUTZ brings to bear, we feel that the company will be able to sell $3,600,4,300,5,200,$ and $3,900$ units each year for the next four years respectively. Again, capitalizing on the name recognition of PUTZ, we feel that a premium price of $$750$ can be charged for each zither. Because zithers appear to be a fad, we feel at the end of the four$-$year period, sales should be discontinued.

PUTZ believes that fixed costs for the project will be $$415,000$ per year, and variable costs will be $10$ percent of sales. The equipment necessary for production will cost $$3\mathrm{.}5$ million and will be depreciated according to a three$-$year MACRS schedule:
