Alternative A has a first cost of $3,315,000 Maintenance cost will start end of year three due to an incentive in the contract with the manufacture that will give free maintenance in the first 2 years. The maintenance cost at end of year three is $42,000 and will increase by $2,700 starting end of year four and continue to increase with the same value thereafter till the end of its service life.
