Calculate a plantwide predetermined overhead rate using direct labor hours as the cost driver.

Calculate a plantwide predetermined overhead rate using machine hours as the cost driver.

Using the plantwide rate calculated on the basis of direct labor hours, how much overhead would be applied to a job requiring 25 direct labor hours?

Using the plantwide rate calculated on the basis of machine hours, how much overhead would be applied to a job requiring 5 machine hours?

Crystal is considering the use of department overhead rates. Assume that the cost driver for the molding department is machine hours.
