PA$2-7($Static$)$ Selecting an Allocation Base and Analyzing Manufacturing Overhead $[$LO $2-3,2-5]$

Amberjack Company 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:

$$Estimated ValueActual ValueManufacturing overhead cost$ $594,000$$ $655,000$Direct labor cost$ $396,000$$ $450,000$Direct labor hours$16,500$hours$18,000$hoursMachine hours$7,500$hours$8,500$hours

Required:

Based on the company$$s current allocation base $($direct labor hours$),$ compute the following:

Predetermined overhead rate.Applied manufacturing overhead.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:

Predetermined overhead rate.Applied manufacturing overhead.Over$-$ or underapplied manufacturing overhead.

If the company had used machine hours $($instead of direct labor hours$)$ as its allocation base, compute the following:

Predetermined overhead rate.

Note: Round your answer to $2$ decimal places.

Applied manufacturing overhead.

Note: Round your intermediate calculations to $2$ decimal places.

Over$-$ or underapplied manufacturing overhead.

Note: Round your intermediate calculations to $2$ decimal places.

Based on last year$$s data alone, which allocation base would have provided the most accurate measure for applying manufacturing overhead costs to production?
