Troski Corporation sells a number of products to groups that provide educational workshops and seminars. One of the products involves a combination leather case and note pad. The company purchases the case and pad combination from a supplier and encloses a AED3 pen that contains the educational groups' name and logo.

Troski began to carry this product at the start of 2019, acquiring 12,500 cases from Executive Supply for AED87,500 along with an identical number of pens from Accent Goods. During 2019, 9,500 of the cases and pens were issued to Troski's assembly operation where the pen is added. Eighty percent of these cases were completed as of December 31, and a review of the December 31 finished-goods inventory found 2,600 completed cases in the warehouse.

Required:

Determine the cost of the cases and pens that would appear in Troski's raw materials, work in process, and finished-goods inventory as of December 31.
