Answer:
2018 = $4,945.46
2019 - $4,450.91
Step-by-step explanation:
sum-of- the-years'-digits depreciation expense =( number of useful lives remaining / sum of the years ) x (Cost of asset - residual value)
sum of the years = 1 +2 +3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 = 55
depreciation expense in 2018 = (10 / 55 ) x ( $33,600 - $6,400) = $27,200 X 0.181818 = $4,945.46
depreciation expense in 2018 = (9 / 55 ) x ( $33,600 - $6,400) = $27,200 X 0.163636 = $4,450.91
