Hi-Tek produced and sold 70,000 units of B300 at a price of $20 per unit and 17,500 units of T500 at a price of $40 per unit. The companys traditional cost system allocates manufacturing overhead to products using a plantwide overhead rate and direct labor dollars as the allocation base. Additional information relating to the companys two product lines is shown below:

	B300		T500		Total
Direct materials	$	436,300	$	251,700	$	688,000

The company has created an activity-based costing system to evaluate the profitability of its products. Hi-Teks ABC implementation team concluded that $50,000 and $100,000 of the companys advertising expenses could be directly traced to B300 and T500, respectively. The remainder of the selling and administrative expenses was organization-sustaining in nature. The ABC team also distributed the companys manufacturing overhead to four activities as shown below:

	Manufacturing		Activity
Activity Cost Pool (and Activity Measure)	Overhead		B300	T500	Total
Machining (machine-hours)	$	213,500	90,000	62,500	152,500
Setups (setup hours)		157,500	75	300	375
Product-sustaining (number of products)		120,000	1	1	2

Total manufacturing overhead cost	$	608,000

1. Compute the product margins for the B300 and T500 under the companys traditional costing system.

2.

Compute the product margins for B300 and T500 under the activity-based costing system. (Negative product margins should be indicated by a minus sign. Round your intermediate calculations to 2 decimal places.)

3.	Prepare a quantitative comparison of the traditional and activity-based cost assignments. (Round your intermediate calculations to 2 decimal places and "Percentage" answer to 1 decimal place. (i.e. .1234 should be entered as 12.3))
