Answer:
b. $11,760
Explanation:
The computation of the depreciation expense is shown below:
= (Original cost - residual value) ÷ (useful life)
= ($70,800 - $12,000) ÷ (5 years)
= ($58,800) ÷ (5 years)
= $11,760
In this method, the depreciation is same for all the remaining useful life
The Purchase cost is computed below:
= $60,000 + $2,800 + $8,000
= $70,800
