initial cost $8500 $6000
Annual benefit $1800 $1500
Useful life, in years 5 10
If the Minimum Attractive Rate Of Return is 9%, which alternative should be selected using Incremental Analysis?

4.Two alternatives are being evaluated, with the projected live of each machine being 10 years. the cash flows are as follows
Alt A. Alt B.
Initial Cost $550,000 $300,000
Annual Maintenance $30,000 $15,000
Annual Benefit $140,000 $95,000
