1) how do I compute plantwide rate overhead rate based on direct labor hours?

2) How do I find what the total overhead costs assigned to products A and B assuming that overhead costs are allocated using the plantwide rate calculated in part 1

Information:

The overhead costs ($440000) have been divided into four cost pools.

Product Number of Setups number of orders direct labor hours packaging orders total

A 50 150 1000 600

B 10 50 4000 400

Cost per a pool $60000 $100000 $200000 $80000 $440000
