One method for developing a mine will result in the recovery of 62% of the available ore deposit and will cost $23.5 per ton of material removed. A second method will recover only 50% of the ore deposit, but it will cost only $15 per ton of materials removed. Subsequent processing of the removed ore recovers 305 pounds metal from each ton of processed ore and costs $45 per ton of ore processed. The ore contains 305 pounds of metal per ton, which can be sold or $0.85 per pound. Which method for developing the mine should be used
