Aria Acoustics, Inc. $($AAI$),$ projects unit sales for a new seven$-$octave voice emulation

implant as follows:

Production of the implants will require $$1,550,000$ in net working capital to start and

additional net working capital investments each year equal to $15$ percent of the

projected sales increase for the following year. Total fixed costs are $$1,450,000$ per year,

variable production costs are $$240$ per unit, and the units are priced at $$355$ each. The

equipment needed to begin production has an installed cost of $$20,500,000.$ Because

the implants are intended for professional singers, this equipment is considered

industrial machinery and thus qualifies as seven$-$year MACRS property. In five years, this

equipment can be sold for about $20$ percent of its acquisition cost. The tax rate is $25$

percent and the required return on the project is $18$ percent. Refer to Table $8\mathrm{.}3.$
