Answer:
Activity 1 rate driver= $20 per driver
Step-by-step explanation:
Activity-based costing is a form of absorption costing where overheads are charged to product using cost drivers.
Under this method, overheads are first analyzed and categorized by the activities responsible for them and then charged to product based on the amount of benefits enjoyed using cost drivers.
Activity rate per driver is calculated as:
Activity overhead for the period / Total cost drivers for the period
Activity 1 overhead = $18,000
Total expected cost drivers for activity 1 = 500 +400 = 900
Overhead rate per cost driver
= $18,000/900 hours
= $20 per driver
