everything is correct except for fixed overhead volume variance

Norwall Company's budgeted variable manufacturing overhead cost is $1.20 per machine-hour and its budgeted fixed manufacturing overhead is $105,966 per month. The following information is available for a recent month: a. The denominator activity of 33,640 machine-hours is used to compute the predetermined overhead rate. b. At a denominator activity of 33,640 machine-hours, the company should produce 11,600 units of product. c. The company's actual operating results were: Required: 1. Compute the predetermined overhead rate and break it down into variable and fixed cost elements. (Round your onswers to 2 decimal places.) 2. Compute the standard hours allowed for the actuat production. 3. Compute the variable overhead rate and efficiency variances and the fixed overhead budget and volume variances. (Indicote the effect of each variance by selecting " F " for fovorable, " U " for unfavorable, and "None" for no effect (i.e., zero variance), Input all amounts as positive values. Round your intermediate calculations and final answers to 2 decimal places.)
