Norwall Company's variable manufacturing overhead should be $1.30 per standard machine-hour and its fixed manufacturing overhead should be $26,040 per month.

The following information is available for a recent month:

a.	The denominator activity of 8,400 machine-hours is used to compute the predetermined overhead rate.
b.	At the 8,400 standard machine-hours level of activity, the company should produce 4,000 units of product.
c.	The companys actual operating results were:

Number of units produced		5,240
Actual machine-hours		9,060
Actual variable manufacturing overhead cost	$	10,419
Actual fixed manufacturing overhead cost	$	28,300

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.)
