Answer:

1.A

2014 Depreciation

Straight line method $26,667

Units-of-output $34,560

Double declining balance $57,933

2015 Depreciation

Straight line method $26,667

Units-of-output $26,840

Double declining balance $19,311

2016 Depreciation

Straight line method $26,667

Units-of-output $18,600

Double declining balance $6,437

1.B Total Depreciation in 3 years

Straight line method $80,000

Units-of-output $80,000

Double declining balance $83,681

2. Double declining balance yields the highest depreciation expense over the three-year life of an equipment

Explanation:

1.A In computing straight line method, the formula would be:

(cost of equipment - salvage value) / life of equipment

2014

(86,900 - 6,900) / 3 years = 26,667

2015

(86,900 - 6,900) / 3 years = 26,667

2016

(86,900 - 6,900) / 3 years = 26,667

TOTAL DEPRECIATION IN 3 YEAR LIFE OF EQUIPMENT = $80,001 ($26,667 + $26,667 + $26,667)

UNITS-OF-OUTPUT METHOD

Formula: (Cost of equipment - salvage value) / total operating hours of equipment x operating hours used for the year

2014

($86,900 - 6,900) / 20,000 x 8,640

($80,000 / 20,000) x 8,640

$4 per hour x 8,640 = $34,560

2015

$86,900 - 6,900) / 20,000 x 6,710

($80,000 / 20,000) x 6,710

$4 per hour x 6,710 = $26,840

2016

$86,900 - 6,900) / 20,000 x 4,650

($80,000 / 20,000) x 4,650

$4 per hour x 4,650 = $18,600

TOTAL DEPRECIATION IN 3 YEAR LIFE OF EQUIPMENT = $80,000 ($34,560 + $26,840 + $18,600)

DOUBLE DECLINING BALANCE

Formula: 100%/life of equipment x 2

*residual value will not be considered in this method of computation of depreciation expense.

2014

100% / 3 years x 2 = 66,67%

86,900 x 66.67% = $57,933

2015

100% / 3 years x 2 = 66,67%

$86,900 - $57,933 = $28,967

$28,967 x 66.67% = $19,311

2016

100% / 3 years x 2 = 66,67%

$86,900 - ($57,933 + $19,311) = $9,656

$9,656 x 66.67% = $6,437

TOTAL DEPRECIATION IN 3 YEAR LIFE OF EQUIPMENT = $83,681 ($57,933 + $19,311+ $6,437)

2. The method that yields most depreciation over the three-year life of an equipment is the DOUBLE DECLINING METHOD in a total amount of $83,681
