Norwall Company's variable manufacturing overhead should be $1.15 per standard machine-hour and its fixed manufacturing overhead should be $72,864 per month.

The following information is available for a recent month:

1. The denominator activity of 20,240 machine-hours is used to compute the predetermined overhead rate.
2. At the 20,240 standard machine-hours level of activity, the company should produce 9,200 units of product.
3. The companys actual operating results were:

Number of units produced		10,280
Actual machine-hours		21,650
Actual variable manufacturing overhead cost	$	28,145
Actual fixed manufacturing overhead cost	$	76,700

Required:

1. Compute the predetermined overhead rate and break it down into variable and fixed cost elements. (Round your answers to 2 decimal places.)

2. Compute the standard hours allowed for the actual production.

3. Compute the variable overhead rate and efficiency variances and the fixed overhead budget and volume variances. (Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Round your intermediate calculations and final answers to 2 decimal places.)
