Coronado Company is trying to determine the equivalent units of production for conversion costs. Production records indicate that 53000 units were completed and transferred out, and 5500 units in ending work in process were 90% complete as to conversion costs and 100% complete as to materials. There are no beginning units in the department. Materials are added at the beginning of the process, and conversion costs occur evenly throughout the entire production period. What are the equivalent units of production for conversion costs for the current period? 52450 57950 58500 53550
