Clearcopy, a printing company, acquired a new press on January 1, 2019. The press cost $173,400 and had an expected life of 8 years or 4,500,000 pages and an expected residual value of $15,000. Clearcopy printed 675,000 pages in 2019.
Required:
1. Compute 2019 depreciation expense using the:
a. Straight-line method.
b. Double-declining-balance method.
c. Units-of-production method.
2. What is the book value of the machine at the end of 2019 under each method?

Straight-line method

Depreciation expense: $19,800

Book value : $153,600

b. Double-declining-balance method. 

Depreciation expense: $43,350

Book value : $130,050

c. Units-of-production method

Depreciation expense: $23,760

Book value : $149,640

Explanation:

Straight line depreciation expense = (cost of asset - residual value) / useful life

($173,400 - $15,000) / 8 = $19,800

The straight line depreciation method allocates the same deprecation expense for each year of the useful life of the asset.

So, deprecation expense in 2009 would be

$19,800.

Book value = Cost of asset - deprecation expense

$173,400 - $19,800 = $153,600

Depreciation expense using the Double declining method = depreciation factor × cost of asset

Deprecation factor = 2 x (1/useful life) = 2 x (1/8) = 0.25

0.25 x $173,400 = $43,350

Book value = $173,400 - $43,350 = $130,050

Deprecation expense using the unit of production method = deprecation factor × (cost of asset - Salvage value)

Depreciation factor = Total pages printed in 2009 / total pages that can be printed by the machine

675,000 /4,500,000 = 0.15

0.15 x ($173,400 - $15,000) = $23,760

Book value at the end of 2009 = $173,400 - $23,760 = $149,640

I hope my answer helps you

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
