Final answer:
Similar assets purchased in the same year must be depreciated using the same depreciation method, but similar assets purchased in different years can be depreciated using different depreciation methods.
Step-by-step explanation:
Similar assets purchased in the same year must be depreciated using the same depreciation method, but similar assets purchased in different years can be depreciated using different depreciation methods.
For example, if a company purchases multiple computers in the same year, they would use the same depreciation method (e.g. straight-line) to calculate the depreciation expense for each computer.
However, if the company purchases computers in different years, they can choose to use a different depreciation method for each batch of computers.
