A salesman from Industrial Water Services (IWS), who is trying to get his foot in the door of Westco Refining, offered electro-dialysis equipment for $2.5 million. This is $800,000 more than the price offered by a competing saleswoman from AG Enterprises. However, IWS said Westco won’t have to pay for the equipment until the 2-year warranty runs out. IWS will also offer an extended 2-year warranty for $100,000, payable 2 years from now. If Westco does want the extended warranty, determine which offer is better using Westco’s real return requirement of 15% per year and an assumed inflation rate of 3.5% per year.
