Final answer:
The book value of the Toyota Tundra at the end of year 4 is $13,200, and the depreciation taken in the first year, assuming the purchase date of April 12, would be $3,133.
Step-by-step explanation:
The student's question pertains to the calculation of depreciation using the straight-line method and adjusting for partial year depreciation.
Book Value Calculation
To calculate the book value at the end of year 4, we use the formula:
Book Value = Cost of Asset - (Depreciation per Year × Number of Years)
Depreciation per Year = (Cost of Asset - Residual Value) / Useful Life
Plugging in the numbers for Lena Horn's Toyota Tundra gives us:
Depreciation per Year = ($30,800 - $4,400) / 6 = $4,400
Book Value at End of Year 4 = $30,800 - ($4,400 × 4) = $13,200
First Year Depreciation Calculation
When accounting for partial year depreciation, the depreciation expense is prorated based on the number of months the asset is in service. Since the Tundra was bought on April 12, it would be in service for approximately 8.5 months in the first year.
First Year Depreciation = Depreciation per Year × (Months of Service / 12)
First Year Depreciation = $4,400 × (8.5 / 12) = $3,133 (rounded to the nearest dollar)
