Operating and Maintenance costs are $1250 for the first year and expected to increase by $1397 thereafter. Brand B: machine costs $10429 and is expected to have a scrap value of $8936 whenever it is retired. Operating and Maintenance costs are $1409 for the first year and expected to increase by $1113 thereafter. If the MARR is 11%, determine the minimum equivalent uniform annual cost associated with the optimal economic life of the machine that offers the lowest EUAC.
