In January 2017, installation costs of $4,900 on new machinery were charged to Maintenance and Repairs Expense. Other costs of this machinery of $24,500 were correctly recorded and have been depreciated using the strsight-line method with an estimated life of 10 years and no salvage value. At December 31, 2018, it is decided that the machinery has a remaining useful life of 20 years, starting with January 1, 2018. What entries should be made in 2018 to correctly record transactions related to machinery, assuming the machinery has no salvage value? The books have not been closed for 2018 and depreciation expense has not yet been recorded for 2018. (Credit account titles are automatically indented when the amount is entered. Do not indent manually. If no entry is required, select "no entry" for the account titles and enter 0 for the amounts).
