Operating and Maintenance costs are $1,760 for the first year and expected to increase by $1,069 thereafter. Brand B: machine costs $12,310 and is expected to have a scrap value of $7,850 whenever it is retired. Operating and Maintenance costs are $1,669 for the first year and expected to increase by $1,991 thereafter.
