The engineering team at Manuel's Manufacturing, Inc., is planning to purchase an enterprise resource planning (ERP) system. The software and installation from Vendor A costs $380,000 initially and is expected to increase revenue $125,000 per year every year. The software and installation from Vendor B costs $280,000 and is expected to increase revenue $95,000 per year. Manuel's uses a 4-year planning horizon and a 10 percent per year MARR.

b) Which ERP system should Manuel purchase if his decision rule is to select the system with the shortest DPBP?
