Hayden Inc. has a number of copiers that were bought four years
ago for $32,000. Currently maintenance costs $3,200 a year, but the
maintenance agreement expires at the end of two years, and
thereafter, the annual maintenance charge will rise to $9,200. The
machines have a current resale value of $9,200, but at the end of
year 2, their value will have fallen to $4,700. By the end of year
6, the machines will be valueless and would be scrapped....
