The predetermined overhead rate and Applied over costs are $3.75 per machine hour and $742,500
A predetermined overhead rate is an allocation rate that is used to apply the estimated cost of manufacturing overhead to cost objects.
Predetermined overhead rate
= estimated total manufacturing overhead costs / estimated machine hours
= 750,000 / 200000
= $3.75 per machine hour
Applied overhead costs
= Actual machine hours * predetermined overhead rate
= 198,000 * 3.75
= $742,500
