Explanation:
a) Data and Calculations:
Activity Centers Cost Drivers Rate per Cost Driver Unit
Materials handling Pounds of material handled $17 per pound
Quality inspections Number of inspections $210 per inspection
Machine setups Number of machine setups $2,600 per setup
Running machines Number of machine-hours $22.00 per hour
Direct materials costs = $300,000
Direct labor costs = $150,000
Pounds of materials = 3,900
Inspections = 790
Setups = 50
Machine usage = 16,000 hours
b) Manufacturing Overhead costs, based on ABC:
Items Per unit cost Units Total cost
Materials handling $17 per pound 3,900 $66,300
Quality inspections $210 per inspection 790 165,900
Machine setups $2,600 per setup 50 130,000
Running machines $22.00 per hour 16,000 352,000
Total manufacturing overhead costs $714,200
b) It is assumed that there are no beginning and ending inventories.
