Answer:
$229,200
Step-by-step explanation:
The carrying value of the machine as of December 31, 2017, was $1,500,000 (purchase cost) - $354,000 (accumulated depreciation) = $1,146,000.
Since the machine's useful remaining life was reduced by 3 years, the depreciation amount should reflect this. The remaining useful life of the machine is 5 years (2018 - 2022), so the company can increase the depreciation expense per year to $1,146,000 / 5 = $229,200.
That way at the end of 2022 the carrying value will be $0, since the machine has no salvage value.
