The brass pump of Problem 1.9 would cost $5000 in- stalled. Instead, George could use a stainless steel pump that has been sitting in the maintenance shop for a year. The pump should last 3 more years. The pump cost $15,000, but it was used for 2 years before being put on the shelf. The accountants say the pump is worth $6000. The maintenance supervisor says that it will cost an extra $500 to recon?gure the pump for the new use and that he could sell it used (as is) for $3000. How much would George save or spend by using the stainless steel pump?
