Answer:
A. depreciation expenses for each under Double declining method
2016 = $19,000
2017 = $9500
2018= $4750
2019= $2,375
Total Accumulated Depreciation = $35,625
Gain on sales of the asset = salvage value + accumulated dpereciation - cost
= $3,500 + $35,625 - $38,000 = $1,125
b. depreciation expenses using unit of production
2016 = $8,970
2017 = $9,430
2018 = $9,660
2019 = $6,900
total accumulated depreciation = $34,960
Gain on the sale of the asset = $3500 + $34,690 - 38,000 = $460
Explanation:
a. Computataion of depreciation expenses uing Double - declining method
annual depreciation = cost minus Accumulated Depreciation x 2/life span
2016 = $38,000 * 2/4 = $19,000
2017 = ( $38,000 - 19,000) * 2/4 = $9,500
2018 = ( $38,000 - 28,500) * 2/4 = $4,750
2019 = ($38,000 - 33,250) * 2/4 = $2,375
b. computation of depreciation expenses using unit of production
Depreciation per unit = (Cost - Salvage value ) * 1/ life unit
= ( $38,000 - 3,500)/1,520,000 = $0.023
depreciation for each year
2016 = $0,023 * 390,000 = $8,970
2017 = $0.023 * 410,000 = $9,430
2018 = $0.023 * 420,000 = $9660
2019 = $0.023 * 300,000 = $6,900
