GrandBlue... I've got a third part to that question...

This is the third and final of three questions asked based on this case study. Please read to the bottom. Another attempt has been made but it does not lead to the correct answer.

Ana Carillo and Associates is a medium-sized company located near a large metropolitan area in the Midwest. The company manufactures cabinets of mahogany, oak, and other fine woods for use in expensive homes, restaurants, and hotels. Although some of the work is custom, many of the cabinets are a standard size.

One such non-custom model is called Luxury Base Frame. Normal production is1,000units. Each unit has a direct labor hour standard of5hours. Overhead is applied to production based on standard direct labor hours. During the most recent month, only680units were produced;4,500direct labor hours were allowed for standard production, but only4,000hours were used. Standard and actual overhead costs were as follows.

Standard (1,000units); Actual (680units)

Indirect materials $9,700; $9,900

Indirect labor 34,700; 41,100

Overhead application rate is $23.22 (this was placed into the module and confirmed correct).

Applied overhead: $104,490 (this was placed into the module and confirmed correct).

How do I calculate the controllable variance?
