A mine installed a pumping system costing $24,298 to transfer mine water. The pump has no salvage value. The O&M cost for the pump is very high (i.e., $6,153 in the first year and increasing incrementally by an additional $5,918 each year thereafter). Assume that the discount rate is 15% and determine economic life of the pump by creating an EUAC versus time graph. In the space below, enter the EUAC for the optimal life span. Note: please enter a positive value for the EUAC.
