A machine can be purchased for $207,000 and used for five years, yielding the following net incomes. In projecting net incomes, double-declining depreciation is applied, using a five-year life and a zero salvage value.

	Year 1				Year 2				Year 3				Year 4				Year 5
Net income		$	16,500			$	38,000			$	62,000			$	44,000			$	116,000
