Parkway Company incurred $140,000 in material costs during July. Additionally, the 13,400 units in the Work-in-Process Inventory on July 1 had materials assigned to them of $46,000, even though they were only 10% complete as to materials. No additional units were started during July, and there were no unfinished units on hand on July 31. What is the material cost per unit for July, assuming Parkway uses weighted-average process costing?
