Answer:
Way Cool:
1. Overhead cost per unit for each product line:
Model 145 Model 212
Machine hours 2,280 5,400
Numbers of units 1,600 3,200
Total costs $498,441.25 $1,180,518.75
Overhead cost
per unit $311.53 $368.91
2. Total cost per unit if the direct labor and direct materials costs per unit are $200 for Model 145 and $130 for Model 212
Model 145 Model 212
Overhead cost
per unit $311.53 $368.91
Direct material &
labor cost per unit $200.00 $130.00
Total cost per unit $511.53 $498.91
3. Determination of profit or loss per unit if market price for Model 145 is $732 and $490 for Model 212:
Model 145 Model 212
Sales price $732.00 $490.00
Cost of sales $511.53 $498.91
Profit (Loss) per unit $220.47 ($8.91)

Additional production information concerning its two product lines follows.
Model 145 Model 212 Total
Units produced 1,600 3,200 4,800
Welding hours 2,000 2,900 4,900
Batches 405 405 810
Number of inspections 485 330 815
Machine hours 2,280 5,400 7,680
Setups 40 40 80
Rework orders 130 100 230
Purchase orders 350 175 525
b) Calculation of Plantwide overhead rate based on machine hours:
Total overhead costs/machine hours = $1,678,960/7,680
= $218.6146 per machine hour
c) Activity Based Costing system is a system that accumulates and allocates production or service costs based on the activities undertaken for the production or service. The activities are regarded as the cost drivers and therefore better bases for accumulating and allocating costs.
