I am stuck on this question as well.

Performance Castings Inc. casts blades for turbine engines. Within the Casting Department, alloy is first melted in a crucible, then poured into molds to produce the castings. On March 1, there were 900 pounds of alloy in process, which were 30% complete as to conversion. The Work in Process balance for these 900 pounds was $92,970, determined as follows:

Direct materials (900 x $100)	$90,000
Conversion (900 x 30% x $11)	2,970
	$92,970

During March, the Casting Department was charged $816,000 for 8,500 pounds of alloy and $34,000 for direct labor. Factory overhead is applied to the department at a rate of 150% of direct labor. The department transferred out 8,700 pounds of finished castings to the Machining Department. The March 31 inventory in process was 10% complete as to conversion.
