Isadore's Implements, Inc., manufactures pens and mechanical pencils often used for gifts. Overhead costs are currently allocated using direct labor-hours, but the controller has recommended an activity-based costing system using the following data: Cost Driver Volume Activity Cost Driver Cost Pencils Pens Setting up Number of setups $ 113,400 23 31 Inspecting Number of parts 28,000 3 7 Packing and shipping Number of boxes shipped 52,000 45,000 85,000 Total overhead $ 193,400 Required: (a) Compute the amount of overhead to be allocated to each product under activity-based costing. (Do not round your intermediate calculations. Omit the "$" sign in your response.) Overhead Pencils $ Pens $ (b) Compute the amount of overhead to be allocated to each product using labor-hours as the allocation base. Assume that the number of labor-hours required to assemble each box is 0.2 for pencils and 0.2 for pens and that 45,000 boxes of pencils and 85,000 boxes of pens were produced during the period. (Do not round the cost per hour and round your final answers to nearest dollar amount. Omit the "$" sign in your response.) Overhead Pencils $ Pens $
