The management of International Aluminum Co. is considering whether to process aluminum ingot further into rolled aluminum. Rolled aluminum can be sold for $2,500 per ton, and ingot can be sold without further processing for $1,250 per ton. Ingot is produced in batches of 89 tons by smelting 550 tons of bauxite, which costs $103 per ton of bauxite. Rolled aluminum will require additional processing costs of $610 per ton of ingot, and 1.25 tons of ingot will produce 1 ton of rolled aluminum
