The company has always used direct labor hours to assign manufacturing overhead to products, but it is trying to decide whether it should use a different allocation base such as direct labor dollars or machine hours. Actual and estimated data for manufacturing overhead, direct labor cost, direct labor hours, and machine hours for the most recent fiscal year are summarized here:

Estimated Value Actual Value
Manufacturing overhead cost $732,000 $842,000
Direct labor cost $366,000 $377,000
Direct labor hours 14,640 hours 16,600 hours
Machine hours 18,300 hours 17,500 hours

Required:
Based on the company’s current allocation base (direct labor hours), compute the following:
a. Predetermined overhead rate.
b. Applied manufacturing overhead.
c. Over- or underapplied manufacturing overhead.
