Redo Problem 14.24 with the following additional information.
• The old asset has been depreciated according to a five-year MACRS.
• The new asset also will be depreciated under a five-year MACRS class.
• The marginal tax rate is 30%, and the firm's after-tax MARR is 11%.
In Problem 14.24
An existing asset that cost $16,000 two years ago has a market value of $ 12,000 today, an expected salvage value of $2,000 at the end of its remaining useful life of six more years, and annual operating costs of $4,000. A new asset under consideration as a replacement has an initial cost of $10,000, an expected salvage value of $4,000 at the end of its economic life of three years, and annual operating costs of $2,000. It is assumed that this new asset could be replaced by an-other one identical in every respect after three years at a salvage value of $4,000, if desired. Use a MARR of 11 %, a six-year study period, and PW calculations to decide whether the existing asset should be replaced by the new one.
