$285,000$

$399,000$

Production of the implants will require $$1,510,000$ in net working capital to start and additional net working capital investments each year equal to $10$ percent of the projected sales increase for the following year. Total fixed costs are $$1,410,000$ per year, variable production costs are $$220$ per unit, and the units are priced at $$335$ each. The equipment needed to begin production has an installed cost of $$20,100,000.$ 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 $15$ percent of its acquisition cost. The tax rate is $24$ percent and the required return on the project is $17$ percent.
