Kunkel Company makes two products and uses a conventional costing system in which a single plantwide predetermined overhead rate is computed based on direct labor-hours. Data for the two products for the upcoming year follow: These products are customized to some degree for specific customers. Required: The company's manufacturing overhead costs for the year are expected to be $900,000. Using the company's conventional costing system, compute the unit product costs for the two products.

This time is expected to be distributed as follows during the upcoming year: Compute the unit product costs for the two products using the proposed ABC system
