Net Present ValueUnequal Lives

Healey Development Company has two competing projects: an electric shovel and a processing mill. Both projects have an initial investment of $624,128. The net cash flows estimated for the two projects are as follows:

	Net Cash Flow
Year	Electric Shovel				Processing Mill
1	$199,000				$249,000
2	177,000				231,000
3	177,000				213,000
4	141,000				219,000
5	107,000
6	90,000
7	78,000
8	78,000

The estimated residual value of the electric shovel at the end of Year 4 is $250,000.
