The Cooper Company is considering investing in a recuperator. The recuperator will have an initial cost of \($20,000\) and a service life of 10 years. Operating and maintenance costs for the first year are estimated to be \($1,500,\) increasing by \($100\) every year thereafter. It is estimated that the salvage value of the recuperator will be 20 percent of its initial cost. The recuperator will result in equal annual fuel savings throughout its service life. Assuming MARR is 12 percent, what is the minimum value of fuel savings for which the recuperator is attractive?
