Final answer:
To compare the two alternative rates of depreciation, calculate the depreciation expense for each rate. Multiply the annual depreciation expense by the respective year to get the depreciation expense for the first two years. Subtract the depreciation expenses of 150% declining-balance from double-declining balance to find the excess.
Step-by-step explanation:
To compare the two alternative rates of depreciation, we first need to calculate the depreciation expense for each rate. The double-declining balance method is calculated by taking the straight-line rate and doubling it. The 150% declining-balance method is calculated by taking 150% of the straight-line rate. The straight-line rate is calculated by dividing the cost of the equipment by its useful life.
For the double-declining balance method: Annual depreciation expense = ($86,000 / 8) x 2 = $21,500
For the 150% declining-balance method: Annual depreciation expense = ($86,000 / 8) x 1.5 = $12,750
To compare the first two years, we simply multiply the annual depreciation expense by the respective year. For Year 1, multiply by 1 and for Year 2, multiply by 2.
Double-Declining Balance Depreciation: Year 1 = $21,500, Year 2 = $43,000
150% Declining-Balance Depreciation: Year 1 = $12,750, Year 2 = $25,500
To find the excess of double declining-balance over 150% declining-balance, subtract the depreciation expenses of 150% declining-balance from double-declining balance for each year.
Excess of Double Declining-Balance over 150% Declining-Balance: Year 1 = $21,500 - $12,750 = $8,750, Year 2 = $43,000 - $25,500 = $17,500
