Helix Corporation uses the weighted-average method in its process costing system. It produces prefabricated flooring in a series of steps carried out in production departments. All of the material that is used in the first production department is added at the beginning of processing in that department. Data for May for the first production department follow:

	Units	Percent Complete
		Materials	Conversion
Work in process inventory, May 1	54,000	100%	50%
Work in process inventory, May 31	34,000	100%	30%
Materials cost in work in process inventory, May 1			$ 46,600
Conversion cost in work in process inventory, May 1			$ 12,600
Units started into production			243,600
Units transferred to the next production department			263,600
Materials cost added during May			$ 42,680
Conversion cost added during May			$ 181,798

Required:

1. Calculate the first production department's equivalent units of production for materials and conversion for May.

2. Compute the first production department's cost per equivalent unit for materials and conversion for May.

3. Compute the first production department's cost of ending work in process inventory for materials, conversion, and in total for May.

4. Compute the first production department's cost of the units transferred to the next production department for materials, conversion, and in total for May.
