*Nettle Company uses process costing to account for the production of rubber balls. All direct materials are added at the beginning of the process, and conversion costs are incurred uniformly throughout the process. Equivalent units have been calculated to be 12,800 units for materials and 12,500 units for conversion costs. Beginning inventory consisted of $6,000 in materials and $7,125 in conversion costs. April costs were $50,560 for materials and $53,750 for conversion costs. Ending inventory still in process consisted of 6,250 units (100% complete for materials, 50% for conversion). The total cost per equivalent unit using the FIFO method would be:
