Consider the following independent situations. Situation 1: Ducharme Corporation purchased electrical equipment at a cost of $62,000 on June 2, 2017. From 2017 through 2020, the equipment was depreciated on a straight-line basis, under the assumption that it would have a 10-year useful life and a $12,000 residual value. After more experience and before recording 2021's depreciation, Ducharme revised its estimate of the machine's useful life downward from a total of 10 years to 8 years, and revised the estimated residual value to $10,000. On April 29, 2022, after recording part of a year's depreciation for 2022, the company traded in the equipment on a newer model, and received a $20,000 trade-in allowance, even though the equipment's fair value was only $14,000. The new asset had a list price of $76,500 and the supplier accepted $56,500 cash for the balance. The new equipment was depreciated on a straight-line basis, assuming a seven-year useful life and a $6,500 residual value. Required #1: 1. Journal Entry on June 02, 2017. 2.
