Street Smarts, Inc., mass-produces street lights. Materials used in constructing the body of the lights are added at the start of the process, while the materials used in wiring the lights are added at the halfway point. All labor and overhead are added evenly throughout the manufacturing process. Street Smarts uses process costing and had the following unit production information available for the months of March and April.
