Gunston Processing produces two products, ALT$-1$ and ALT$-2,$ from a batch using a single raw material, ALT$-0.$ Both products require further processing before they be can be sold. A batch of ALT$-1$ can be sold for $$150,000$ after processing costs of $$30,000.$ A batch of ALT$-2$ can be sold for $$240,000$ after further processing. The cost of ALT$-0$ is $$200,000$ for a batch. Using the estimated net realizable value method, a joint cost of $$120,000$ was allocated to ALT$-2$ for a batch.
