Dexter Industries purchased packaging equipment on January 8 for $57,600. The equipment was expected to have a useful life of three years, or 14,400 operating hours, and a residual value of $3,600. The equipment was used for 5,760 hours during Year 1, 4,320 hours in Year 2, and 4,320 hours in Year 3.

Also determine the total depreciation expense for the three years by each method. Round the final answers for each year to the nearest whole dollar.

Year 1		$			$			$
Year 2		$			$			$
Year 3		$			$			$
