A conveyor system is needed at a coal mine with an expected life span of 20 years. Two options are available. Option A involves used equipment and would cost $1,500,000 to purchase with $120,000 in annual 0&M costs, while Option B involves new equipment and would cost $2,200,000 to purchase with $100,000 in annual 0&M costs. Statistical analyses indicate that the used conveyor equipment (Option A) has a probability of failure in a given year of 10% and a 9-year useful life, while the new equipment (Option B) has a probability of failure in a given year of 3% with a 40-year useful life. Failure of the conveyor system at any time will require 50% reinvestment of initial cost for repairs. At the end of their useful life, the equipment is retired and another purchase is reqiored (cannot be repaired). The effective interest rate is 6%, and salvage values can be ignored. Determine the better option by calculating the difference between the expected equivalent uniform annual cost (EUAC) of the two options.
