Cirrus Logic is trying to decide on an allocation base to use to assign manufacturing

overhead to jobs. 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:

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.

If the company had used direct labor dollars $($instead of direct labor hours$)$ as its

allocation base, compute the following:

a$)$ Predetermined overhead rate.

b$)$ Applied manufacturing overhead.

c$)$ Over$-$ or underapplied manufacturing overhead.

If the company had used machine hours $($instead of direct labor hours$)$ as its

allocation base, compute the following:
