Effect of By-Product versus Joint Cost Accounting: Ninja Turtle Company processes input Leonardo into three outputs: Michaelangelo, Raphael, and Donatello. Michaelangelo accounts for 70 percent of the net realizable value at the split-off point, while Raphael accounts for 25 percent. The balance is accounted for by Donatello. The joint costs total $159,050. If Donatello is accounted for as a by-product, its net realizable value at split-off of $9,900 would be credited to the joint manufacturing costs using method 1 described in the text (see Illustration 6-8).

Required: What are the allocated joint costs for the three outputs:

a. If Donatello is accounted for as a joint product?

b. If Donatello is accounted for as a by-product?
