Answer:
$1350
Step-by-step explanation:
Straight line depreciation expense = (Cost of asset - Salvage value) / useful life
depreciation expense under the initial assumptions
($11,000 - $2,200) / 4 = $2200
Accumulated depreciation at the end of year 2 = $2200 x 2 = $4400
Book value at the beginning of year 3 = $11,000 - $4400 = $6600
Depreciation expense using the new assumptions
($6600 - $1200) / 4 = $1350
