A present asset (defender) has a current market value of $85,000 (year 0 dollars). Estimated market values at the end of the next three years, expressed in year 0 dollars, are MV₁=$73,000, MV₂=$60,000, MV₃=$40,000. The annual expenses (expressed in year 0 dollars) are $15,000 and are expected to increase at 4.5% per year. The before-tax nominal MARR is 15% per year. The best challenger has an economic life of 5 years and its associated EUAC is $39,100. Market values are expected to increase at the rate of inflation which is 3% per year. Based on this information and a before-tax analysis, what are the marginal costs of the defender each year and when should you plan to replace the defender with the challenger?

Peason's gave me the answers, but i'm not sure how to get them. Thanks
