Blasto, Inc., operates several mines. At one, a typical batch of ore run through the plant yields three products: lead, copper, and manganese. At the split-off point, the intermediate products cannot be sold without further processing. The lead from a typical batch sells for $160,000 after incurring additional processing costs of $48,000. The copper is sold for $320,000 after additional processing costs of $40,000, and the manganese yield sells for $240,000 but requires additional processing costs of $72,000. The joint costs of processing the raw ore, including the cost of mining, are

$400,000 per batch.

Required Use the estimated net realizable value method to allocate the joint processing costs.
