Problem 9-9A

Megan Corporation Corporation purchased machinery on January 1, 2017, at a cost of $250,000. The estimated useful life of the machinery is 4 years, with an estimated salvage value at the end of that period of $30,000. The company is considering different depreciation methods that could be used for financial reporting purposes.

If someone could explain to me the steps on how to achieve these answers that would be amazing!
