Each year, Acme Company extracts 12,000 pounds of mineral XZ from its mine at a cost of $25 per pound. Acme can sell the raw XZ for $31 a pound or process it further into metal ingots. The incremental variable costs of selling raw XZ are $4 per pound and there are no incremental fixed costs. It takes three pounds of XZ to make one ingot, which Acme can sell for $225 per ingot. Acme can make and sell up to 4,000 ingots per year. The incremental variable costs are $48 per ingot and the annual traceable fixed costs related to producing and selling ingots include $258,000 of salaries and $103,000 of depreciation on production equipment that has no resale value. How much higher is Acme’s annual operating income if it produces and sells ingots as opposed to selling the raw XZ as is?
