Answer:
To calculate the book value of the $2,500 computer after 5 years using the MACRS rates, you need to apply the depreciation rates for each year to the original cost of the computer.
Year 1: 20.0% depreciation
Depreciation for Year 1 = $2,500 * 20.0% = $500
Book value after Year 1 = $2,500 - $500 = $2,000
Year 2: 32.0% depreciation
Depreciation for Year 2 = $2,000 * 32.0% = $640
Book value after Year 2 = $2,000 - $640 = $1,360
Year 3: 19.2% depreciation
Depreciation for Year 3 = $1,360 * 19.2% = $261.12
Book value after Year 3 = $1,360 - $261.12 = $1,098.88
Year 4: 11.52% depreciation
Depreciation for Year 4 = $1,098.88 * 11.52% = $126.58
Book value after Year 4 = $1,098.88 - $126.58 = $972.30
Year 5: 11.52% depreciation
Depreciation for Year 5 = $972.30 * 11.52% = $111.94
Book value after Year 5 = $972.30 - $111.94 = $860.36
So, the book value of the $2,500 computer after 5 years would be $860.36 (rounded to the nearest hundredth).
