PROBLEMS
9-1. Q: An engineer proposes to buy a machine for $100,000 today that will save $60,000 in labor
costs at the end of each of the next two years. If the company demands a 15% retum on
investments such as this, what is the net present worth (NPW) of the proposal? Should it be
funded?
9.2. Q: Your company has two alternative opportunities, each requiring your entire capital investment
budget of $325,000. Alternative A will return $390,000 at the end of one year; alternative B will
return $216,000 at the end of each of the first two years. Which (if either) alternative should you
recommend on the basis of (a) simple payback time?; (b) net present worth?
9-3. Q: If you have been exposed to capital investment analysis and/or engineering economy,
comment on the proposal to invest $1,000,000 in a new product now that is projected to generate
$200,000 profit at the end of each year for eight years, assuming that your company requires 15%
return on investment before taxes.
A: The present worth of a net profit of a dollar at the end of each of eight years at a 15% discount
