Final answer:
The journal entries for the transactions involve recognizing the disposal of fixed assets, recording the sale of machinery, expensing repair costs, capitalizing the replacement of a special base, and expensing the repainting of a building.
Step-by-step explanation:
When approaching the accounting transactions presented, we must consider the principles of depreciation and expense recording. Since the question requests general journal entries for the transactions, we identify the nature of each transaction to treat them appropriately in the financial statements. Depreciation expense is applied to machinery and buildings, and any costs enhancing the benefits of assets or restoring them are capitalized, while costs that merely maintain assets are expensed.
- Building demolition: The building cost is removed from the books, along with accumulated depreciation to date. The payment to the contractor is recorded as an expense.
- Machinery sale: The machinery's book value is removed, recognizing any gain or loss on the sale. The cash receipt and freight costs are also recorded.
- Gear replacement: Since the gear replacement makes the machine more efficient, but does not extend its useful life, the cost is expensed.
- Special base replacement: The defective base's cost is removed from the books, and the new base cost is capitalized.
- Building repainting: Repainting a building is typically an expense as it maintains the property rather than enhances its value.
