Barton and Barton Company (B\&B) purchased construction equipment for $79 million. The equipment was placed in service at the beginning of 201. Manegement estimated the equipment's residual value to be $2 million and used the sum-of-the-years'-digits method to depreciate the equipment over a 10-year life. At the beginning of 204, B\&B decided to change to the straight-tine method. Ignoring income taxes, prepare the journal entry relating to the equipment for 204.
