Your company has prepared forecasts for the development costs
and operating profi ts of the next generation of your product.
Development costs for each of the next three years (Years 1 to
3) will be $50,000. Manufacturing equipment costing $100,000
will be purchased at the end of Year 3. Annual profi ts for the
fi ve-year product life (from Year 4 to Year 8) are projected to be
$80,000. The salvage value of the manufacturing equipment at
the end of Year 8 is $20,000. Given a 12% discount rate, should
