Kramerica Inc is engaged in the business of mining gold using a process that pumps water from underground mines and then filters the gold out of the water. The current equipment they use to pump from the mines is three years old (the cost was $5,000,000) three years ago), and the IRS allows such equipment to be depreciated straight line over a 5-year period. The equipment, however, is expected to last another five years (so total life is 8 years). Today, the old equipment can be sold for $1,500,000. The older machinery requires a lot of maintenance, and the cost of operating it is $2,000,000 per year
