For each unit of output, agriculture requires inputs of 0.20 unit from agriculture, 0.40 unit from manufacturing, and 0.20 unit from services. For each unit of output, manufacturing requires inputs of 0.30 unit from agriculture, 0.20 unit from manufacturing, and 0.20 unit from services. For each unit of output, services requires 0.20 unit from agriculture, 0.30 unit from manufacturing, and 0.30 unit from services. Determine the production levels needed to satisfy a final demand of 0 units for agriculture, 40 units for manufacturing, and 0 units for services. The production level needed from the agricultural sector is 40.00 units." Two men, Joel and Jerry, each pushes an object that are identical on a horizontal frictionless floor starting from rest.

Data for the two products for the upcoming year follow:Mercon Wurcon Direct materials cost per unit $ 9.00 $ 7.00Direct labor cost per unit $15.00 $ 17.00Direct labor-hours per unit 0.40 4.80Number of units produced 4,000 8,000These products are customized to some degree for specific customers.Required:1. The company's manufacturing overhead costs for the year are expected to be $1,600,000. Using the company's conventional costing system, compute the unit product costs for the two products.2. Management is considering an activity-based costing system in which half of the overhead would continue to be allocated on the basis of direct labor-hours and half would be allocated on the basis of engineering design time. This time is expected to be distributed as follows during the upcoming year:Mercon Wurcon TotalEngineering design time (in hours) 8,000 8,000 16,000Compute the unit product costs for the two products using the proposed ABC system.
