3. A company purchased a $60,000 asset with an estimated life of 4 years and expected salvage value of $30,000. If after 4 years, the asset is sold for $20,000. All accounting adjustments between actual and estimated salvage values occur at the time the asset is sold. The gross income before depreciation and taxes of the company is $20,000 per year. Assume that company is profitable in its other activities. a) Compare the present worth of the income taxes if the straight-line depreciation and double-declining-balance depreciation methods are used. b) Compare the present worth of the investment if the straight-line depreciation and double-declining-balance depreciation methods are used. A cash flow table that shows BTCF, depreciation, taxable income, income tax, and ATCF must be constructed to assist in the calculation in each part. (10 pt.) 3.
