During $2019,$ Ryel Company's controller asked you to prepare correcting journal entries for the following three situations:

Machine A was purchased for $$50,000$ on January $1,2014.$ Straight$-$line depreciation has been recorded for $5$ years, and the Accumulated Depreciation account has a balance of $$25,000.$ The estimated residual value remains at $$5,000,$ but the service life is now estimated to be $1$ year longer than estimated originally.

Machine B was purchased for $$40,000$ on January $1,2017.$ It had an estimated residual value of $$5,000$ and an estimated service life of $10$ years. It has been depreciated under the double$-$declining$-$balance method for $2$ years. Now, at the beginning of the third year, Ryel has decided to change to the straight$-$line method.

Machine $C$ was purchased for $$20,000$ on January $1,2018.$ Double$-$declining$-$balance depreciation has been recorded for $1$ year. The estimated residual value of the machine is $$2,000$ and the estimated service life is $5$ years. The computation of the depreciation erroneously included the estimated residual value.

Required:

Prepare any necessary correcting journal entries for each situation. Also prepare the journal entry necessary for each situation to record depreciation expense for $2019$
