Answer:
2017: $1,658
2018: $11,608
Explanation:
First, we need to know the value we are going to depreciate: this is calculated by subtracting from the total asset value, the salvage value. So, the value we are going to depreciate is $ 79,600. With the straight-line method, depreciation is the same amount all years.
The depreciation each year by the straight-line method is:
Depreciation (yearly)= value to depreciate/ useful life years
Depreciation( yearly)= $79,600/8
Depreciation (yearly)= $9,950
Then, in October 1, 2018 the depreciation expense will be $9,950
Because we need the depreciation expense for december 31, 2017, we need to know the depreciation expense each month. To do so, we divide the yearly depreciation into 12 (12 months):
Depreciation (monthly)= $9,950/12
Depreciation (monthly)= $829.16
The depreciation expense for 2017 is: $ 829.16*2= $1,658.32
Rounded to 0 decimal places: $1,658
The depreciation expense for 2018 is: $9,950+(829.16*2)= 11,608.32
Rounded to 0 decimal places: $11,608
