Explanation:

a. When depreciation method is changed, company is not required to pass any entry altering previous year depreciation amount. This is to avoid unnecessary task of preparing previous year financial statements to reflect this change. The method is simply adopted and carried forward in future years.

b. Cost of machinery = $60,000

Salvage value (original) = $4,000

Useful life = 8 years

Annual depreciation =

                                  = $7,000

Depreciation was charged for 5 years. So, total depreciation charged = 7,000 × 5 = $35,000

Book value of machinery as on 2021 is 60,000 - 35,000 = $25,000

in 2021, it was estimated that useful life of machinery is 10 years

New salvage value is $4,500

Remaining useful life is 10 - 5 = 5 years

Annual depreciation =  

                                  = $4,100

New Annual depreciation = $4,100
