Problem 17-1A Comparing costs using ABC with the plantwide overhead rate LO P1, P3, A1, A2 The following data are for the two products produced by Tadros Company. Direct materials Direct labor hours Machine hours Batches Volume Engineering modifications Number of customers Market price Product A $15 per unit 0.5 DLH per unit 0.4 MH per unit 200 batches 16,000 units 14 modifications 700 customers $55 per unit Product B $30 per unit 1.5 DLH per unit 1.2 MH per unit 360 batches 3,600 units 86 modifications 600 customers $220 per unit The company's direct labor rate is $23 per direct labor hour (DLH). Additional information follows. Costs Driver Indirect manufacturing Engineering support Electricity Setup costs Nonmanufacturing Customer service $ 53,600 Engineering modifications 53,600 Machine hours 160,800 Batches 110,500 Number of customers Required: (Round your per unit cost answers to 2 decimal places and other answers to nearest whole number. Loss amounts should be indicated with minus sign.) Answer is complete but not entirely correct. 1.
