Final answer:
The depreciation expense for year two using double-declining-balance (DDB) method is $1,260, while the depreciation expense using units-of-production (UOP) method is $12,600.
Step-by-step explanation:
Depreciation expense for year two using double-declining-balance (DDB) method can be calculated using the following formula:
DDB = (Book Value at the beginning of the year / Life of the asset) * 2
For the equipment, the book value at the beginning of year one would be $63,000, and the life of the asset is 5 years or 100,000 hours. Therefore, the depreciation expense for year two using DDB method would be:
DDB = ($63,000 / 100,000) * 2 = $1,260
For units-of-production (UOP) method, the depreciation expense is calculated based on the number of hours the equipment is used. In year one, the equipment was used for 19,000 hours, and in year two, it was used for 23,000 hours. Therefore, the depreciation expense for year two using UOP method would be:
UOP = (Cost of equipment - Residual value) * (Hours used in year two / Total estimated hours of life)
UOP = ($63,000 - $3,000) * (23,000 / 100,000) = $12,600.
