Galvanized Products (GP) is considering purchasing a new computer system for their enterprise data management system. The vendor has quoted a purchase price of $100,000. GP is planning to borrow one-fourth of the purchase price from a bank at 15 percent compounded annually. The loan is to be repaid using equal annual payments over a 3-year period. The computer system is expected to last 5 years and has a salvage value of $5,000 at that time. Over the 5-year period, Galvanized Products expects to pay a technician $2 5,000 per year to maintain the system but will save $55,000 per year through increased efficiences. GP uses a MRR of 18 percentfyear to evaluate investments. Find the ERR and recommend whether GP should purchase the computer system. 4-1")
