Louisa Pharmaceutical Company is a maker of drugs for high blood pressure and uses a process costing system. The following information pertains to the final department of Goodheart's blockbuster drug called Mintia.

Beginning work$-$in$-$process $(40\%$ completed$)800$ units

Transferred$-$in $4,000$ units

Normal spoilage $400$ units

Abnormal spoilage $200$ units

Good units transferred out $3,600$ units

Ending work$-$in$-$process $(1/3$ completed$)600$ units

Conversion costs in beginning inventory $ $2,560$

Current conversion costs $ $6,900$

Louisa calculates separate costs of spoilage by computing both normal and abnormal spoiled units. Normal spoilage costs are reallocated to good units and abnormal spoilage costs are charged as a loss. The units of Mintia that are spoiled are the result of defects not discovered before inspection of finished units. Materials are added at the beginning of the process. Using the weighted$-$average method, answer the following question:

What are the total conversion costs in ending inventory?
