The Woodruff Corporation purchased a piece of equipment three years ago for $230,000. It has an asset depreciation range (ADR) midpoint of eight years. The old equipment can be sold for $90,000.

A new piece of equipment can be purchased for $320,000. It also has an ADR of eight years.

Assume the old and new equipment would provide the following operating gains (or losses) over the next six years.

The firm has a 36 percent tax rate and a 9 percent cost of capital. Should the new equipment be purchased to replace the old equipment?
