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.

	Product A			Product B
Direct materials	$	13 per unit		$	26 per unit
Direct labor hours		0.5 DLH per unit			1.5 DLH per unit
Machine hours		0.4 MH per unit			1.1 MH per unit
Batches		120 batches			240 batches

Nonmanufacturing
Customer service		73,000		Number of customers

(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.)

Which method of product costing gives better information to managers of this company?

Activity-based costing method.

• Plantwide overhead rate method

• Departmental overhead rate method

1. Compute the manufacturing cost per unit using the plantwide overhead rate based on direct labor hours.
