Final answer:
To calculate the income earned for platters, we need to allocate the joint costs based on the number of units produced. The joint cost per unit is $8.07. The income earned for platters is $80,700.
Step-by-step explanation:
To calculate the income earned for platters, we need to allocate the joint costs to the platters and cups based on the number of units produced. The total joint cost is the sum of the materials cost, labor cost, and remixing cost, which is $52,000 + $56,000 + $5,000 = $113,000. Now, we can calculate the joint cost per unit by dividing the total joint cost by the total number of units produced (10,000 platters + 4,000 cups = 14,000 units): $113,000 / 14,000 = $8.07 per unit.
To find the income earned for platters, we multiply the joint cost per unit by the number of platters produced: $8.07 per unit * 10,000 platters = $80,700.
