Final answer:
The depreciation expense for the third year would be $13,333.33.
Step-by-step explanation:
To calculate the depreciation expense for the third year, we need to consider the revised estimated life of the tow truck and its new estimated salvage value. The initial estimated life was 10 years with a salvage value of $12,000. However, after three years, the company decided to revise the estimated life to 6 years and the salvage value to $2,000.
To calculate the depreciation expense for the third year, we can use the straight-line depreciation method. This method evenly distributes the cost of the asset over its estimated life. The depreciation expense for each year is determined by subtracting the salvage value from the original cost and dividing it by the estimated life of the asset.
In this case, the original cost of the tow truck was $60,000. After three years, the accumulated depreciation would be (3/10) * $60,000 = $18,000. The revised estimated life is 6 years, so the remaining life of the truck is 6 - 3 = 3 years. The remaining cost of the truck is $60,000 - $18,000 = $42,000. The depreciation expense for the third year would be ($42,000 - $2,000) / 3 = $13,333.33.
