A company buys $200,000 in fixed assets at the beginning of year one, an additional $25,000 at the beginning of year two, and $5,000 at the beginning of year three. Assume all of these assets have a life expectancy of five years, the company uses straight-line depreciation, and there is no salvage value for any of the fixed assets. What are the total amounts of depreciation expense for each of years one, two, and three?
