Problem 1. DuoMed, Inc., manufactures and sells diagnostic equipment used in the medical profession. Its job costing system was designed using an activity-based costing approach. Direct materials and direct labor costs are accumulated separately, along with information concerning four manufacturing overhead cost drivers (activities). Assume that the direct labor rate is $25 per hour and that there were no beginning inventories. The following information was available for 2010, based on an expected production level of 354,167 units for the year:

Calculate the total manufacturing costs and the cost per unit produced and tested during the month of August for MedTech, Inc. (Round "Cost per unit" to 2 decimal places.)
Problem 2: Hammerslay Industries manufactures and sells custom-made windows. Its job costing system was designed using an activity-based costing approach. Direct materials and direct labor costs are accumulated separately, along with information concerning three manufacturing overhead cost drivers (activities). Assume that the direct labor rate is $14 per hour and that there were no beginning inventories. The following information was available for 2010, based on an expected production level of 54,700 units for the year, which will require 235,000 direct labor hours:

(a) Calculate the total manufacturing costs and the cost per unit of the windows produced during the month of March (using the activity-based costing approach). (Round "cost per unit produced" to 2 decimal places and the rest to the nearest dollar amount.)
(b) Assume instead that Hammerslay Industries applies manufacturing overhead on a direct labor hours basis (rather than using the activity-based costing system previously described). Calculate the total manufacturing cost and the cost per unit of the windows produced during the month of March. (Hint: You will need to calculate the predetermined overhead application rate using the total budgeted overhead costs for 2010.) (Do not round your intermediate calculations. Round "cost per unit produced" to 2 decimal places and the rest to the nearest dollar amount.)
