River Services is now at the end of the final year of a project. The equipment originally cost $25,500, of which 75% has been depreciated. The firm can sell the used equipment today for $6,100, and its tax rate is 40%. What is the equipment's after-tax salvage value for use in a capital budgeting analysis? Note that if the equipment's final market value is less than its book value, the firm will receive a tax credit because of the sale?
