Final answer:
The amount of depreciation that will be recorded during each of the remaining years of its useful life is $2,000 for the first three years, and $1,800 for the remaining years.
Step-by-step explanation:
To calculate the amount of depreciation that will be recorded during each of the remaining years of the equipment's useful life, we need to calculate the annual depreciation expense for each year.
The straight-line depreciation method allocates an equal amount of depreciation expense for each year over the useful life of the equipment. To calculate the annual depreciation expense, subtract the salvage value from the initial cost and divide it by the useful life in years.
For the first three years, the annual depreciation expense is ($12,000 - $2,000)/5 = $2,000. For the remaining years, after adjusting the salvage value to $1,200 and increasing the useful life to 6 years, the annual depreciation expense is ($12,000 - $1,200)/6 = $1,800.
