Machine A was purchased three years ago for $10,000 and had an estimated market value of $1,100 at the end of its 10-year life. Annual operating costs are $1,050. The machine will perform satisfactorily for the next seven years. A salesman for another company is offering Machine B for $51,000 with an market value of $5,100 after 10 years. Annual operating costs will be $650. Machine A could be sold now for $8,000, and MARR is 13% per year. Using the outsider viewpoint, what is the difference in the equivalent uniform annual cost (EUAC) of buying Machine B compared to continuing to use Machine A; i.e., EUAC(Machine B) EUAC(Machine A). (Do not enter the dollar sign $ with your answer.)
