Assume that the total sales value at the split-off point for product 1 is $50,000 instead of $130,000 and the sales value of product 3 is $2,000 instead of $20,000. Assume also that, because of its relatively low sales value, the firm treats product 3 as a by-product and uses the net realizable value method for accounting for joint costs. What amount of joint cost would be allocated to the three products?
