Answer:
Double Declining Method
Depreciation : Year 1= 27,720
Depreciation : Year 2= 17,740.80
Depreciation : Year 3= 11,354.4
Depreciation : Year 4= 7266.816
Depreciation : Year 5= 4650.76 Residual Value at the end of 5th year = $ 8287
Explanation:
Straight Line Depreciation: (77,000-8,000)/5/77,000=0.18,
Reducing Balance Depreciation Rate: 2*0.18=0.36 or 36% Annual Depreciation Under Declining Balance Method:
Year 1: $77,000 x 36% = $27,720
Depreciation Year 2: ($77,000 - 27,720) x 36% = $17,740.80
Depreciation Year 3: ($77,000 -45460 ) = $31549 x 36% = $11,354.4
Depreciation Year 4: ($77,000 - 56814.4 ) = $20,185.6 x 36% = $ 7266.816
Depreciation Year 5: ($77,000 - 64081.22 ) = $ 12918.78 x 36% = $ 4650.76
At the end of the fifth year the accumulated depreciation will be $ 68,731 and the residual value of the truck will be 77,000 - 68713= 8287 which is almost equal to the given required value.
Under diminishing balance method we add up the depreciation and deduct from the total value and then apply the percent to the remaining value until we arrive at the desired given salvage or residual value.
