Final answer:
To record depreciation expense for buildings, use the double-declining-balance method. Depreciation expense for equipment is calculated using the straight-line method. Amortization expense for the patent is determined by dividing its book value by its estimated lifespan.
Step-by-step explanation:
1. To record depreciation expense for buildings, we need to calculate the annual depreciation. The building has a cost of $541,000 and is depreciated over a 10-year service life using the double-declining-balance method with no residual value. The formula for double-declining-balance depreciation is: (2 / useful life) * book value. In this case, the depreciation would be (2 / 10) * $541,000 = $108,200.
To record depreciation expense for equipment, we need to calculate the annual depreciation. The equipment has a cost of $131,900, an estimated useful life of 9 years, and an estimated residual value of $14,000. The formula for straight-line depreciation is: (cost - residual value) / useful life. In this case, the depreciation would be ($131,900 - $14,000) / 9 = $14,544.
2. To record amortization expense for the patent, we need to divide its book value by its estimated lifespan. The patent has a book value of $46,500 and an estimated lifespan of 5 years. Therefore, the annual amortization expense would be $46,500 / 5 = $9,300.
3. To calculate the book value for each long-term asset at December 31, 2024, subtract the accumulated depreciation or amortization from the cost. The book value for the land remains the same at $66,000. The book value for the building would be $541,000 - $194,760 = $346,240. The book value for the equipment would be $131,900 - $40,744 = $91,156. The book value for the patent would be $77,500 - $27,900 = $49,600.
