Answer:
D
Explanation:
We can use the units-of-production depreciation method to calculate the depreciation in year 3, since we know the estimated life of the machine in terms of units produced.
First, we need to calculate the depreciation per unit:
Depreciation per unit = (Cost - Residual value) / Expected number of units
Depreciation per unit = ($30,200 - $4,000) / 150,000 units
Depreciation per unit = $0.176 per unit
Next, we can calculate the total depreciation for year 3 based on the number of units produced:
Depreciation for year 3 = Depreciation per unit x Units produced in year 3
Depreciation for year 3 = $0.176 per unit x 40,000 units
Depreciation for year 3 = $7,040
Therefore, the depreciation in year 3 would be $7,040. This corresponds to option D.
