Answer:
YY 2021, disposal of equipment:
Dr Cash 210,000
Dr Accumulated depreciation 170,000
Dr Loss on disposal 20,000
Cr Equipment 400,000
Explanation:
depreciation per unit produced = (cost - resale value) / estimated production = ($400,000 - $50,000) / 700,000 units = $350,000 / 700,000 units = $0.50 per unit
the journal entries should be:
XX 2019, purchase of equipment:
Dr Equipment 400,000
Cr Cash 400,000
December 31, 2019, equipment depreciation:
Dr Depreciation expense 50,000 (= 100,000 units x $0.50)
Cr Accumulated depreciation - equipment 50,000
December 31, 2020, equipment depreciation:
Dr Depreciation expense 80,000 (= 160,000 units x $0.50)
Cr Accumulated depreciation - equipment 80,000
YY, 2019, equipment depreciation:
Dr Depreciation expense 40,000 (= 80,000 units x $0.50)
Cr Accumulated depreciation - equipment 40,000
YY 2021, disposal of equipment:
Dr Cash 210,000
Dr Accumulated depreciation - equipment 170,000
Dr Loss on disposal 20,000
Cr Equipment 400,000
