Consider a system of notebook computers for a college math laboratory. The set of computers costs $10,000 and will be salvaged for $2,000 at the end of a 3-year period. Prepare a depreciation schedule using a 150%-declining balance rate for the system. The depreciation schedule should include the following information for each year: the year’s depreciation, the accumulated depreciation, and the year’s end-of-book value

To prepare a depreciation schedule using a 150%-declining balance rate for the system of notebook computers, follow the steps below:

Step 1: Determine the depreciation rate.
The 150%-declining balance rate can be calculated by dividing 100% by the useful life of the asset. In this case, the useful life is 3 years, so the depreciation rate would be 100% / 3 = 33.33%.

Step 2: Calculate the yearly depreciation.
To calculate the yearly depreciation, multiply the net book value (cost of asset - accumulated depreciation) at the beginning of each year by the depreciation rate.

Year 1: Net Book Value = Cost of asset = $10,000
Year 1 Depreciation = Net Book Value * Depreciation Rate = $10,000 * 33.33% = $3,333.33

Year 2: Net Book Value = Cost of asset - Year 1 Depreciation = $10,000 - $3,333.33 = $6,666.67
Year 2 Depreciation = Net Book Value * Depreciation Rate = $6,666.67 * 33.33% = $2,222.22

Year 3: Net Book Value = Cost of asset - (Year 1 Depreciation + Year 2 Depreciation) = $10,000 - ($3,333.33 + $2,222.22) = $4,444.45
Year 3 Depreciation = Net Book Value * Depreciation Rate = $4,444.45 * 33.33% = $1,481.48

Step 3: Calculate the accumulated depreciation.
The accumulated depreciation is the sum of the yearly depreciations up to that point.

Year 1 Accumulated Depreciation = Year 1 Depreciation = $3,333.33
Year 2 Accumulated Depreciation = Year 1 Depreciation + Year 2 Depreciation = $3,333.33 + $2,222.22 = $5,555.55
Year 3 Accumulated Depreciation = Year 1 Depreciation + Year 2 Depreciation + Year 3 Depreciation = $3,333.33 + $2,222.22 + $1,481.48 = $7,037.03

Step 4: Calculate the end-of-book value.
The end-of-book value is the net book value at the end of each year.

Year 1 End-of-Book Value = Cost of asset - Year 1 Depreciation = $10,000 - $3,333.33 = $6,666.67
Year 2 End-of-Book Value = Net Book Value - Year 2 Depreciation = $6,666.67 - $2,222.22 = $4,444.45
Year 3 End-of-Book Value = Net Book Value - Year 3 Depreciation = $4,444.45 - $1,481.48 = $2,962.97

The depreciation schedule for the system of notebook computers is as follows:

| Year | Depreciation | Accumulated Depreciation | End-of-Book Value |
|------|--------------|--------------------------|-------------------|
| 1 | $3,333.33 | $3,333.33 | $6,666.67 |
| 2 | $2,222.22 | $5,555.55 | $4,444.45 |
| 3 | $1,481.48 | $7,037.03 | $2,962.97 |

Note: The salvage value of $2,000 mentioned in the problem is not considered in the depreciation calculation as it is subtracted from the end-of-book value only after all the depreciation has been accounted for.
