Required:
a. Using the estimates for the year, compute the predetermined overhead rate for each activity (this is step 4 of the activity-based costing process).
b. Using the activity rates calculated in requirement a and the actual cost driver activity levels shown for March, allocate overhead to the three products for the month of March (this is step 5 of the activity-based costing process).
