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 80 tons by smelting 510 tons of bauxite, which costs $105 per ton of bauxite. Rolled aluminum will require additional processing costs of $620 per ton of ingot, and 1.25 tons of ingot will produce 1 ton of rolled aluminum. Required: Question Content Area 1. Prepare a differential analysis as of February 5 to determine whether to sell aluminum ingot (Alternative 1) or process further into rolled aluminum (Alternative 2). If required, do not round interim calculations. If required, use a minus sign to indicate a loss
