Norwall Company's budgeted variable manufacturing overhead cost iS $1.95 per machine-hour and its budgeted fixed manufacturing overhead is $51,336 per month. The following information is available for a recent month: a. The denominator activity of 28,520 machine-hours is used to compute the predetermined overhead rate b. At a denominator activity of 28,520 machine-hours, the company should produce 12,400 units of product. C. The company's actual operating results were Number of units produced Actual machine-hours Actual variable manufacturing overhead cost Actual fixed manufacturing overhead cost 13,390 29,780 S 53,604 S 50,900 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 unfevorable, and "None" for no effect (l.e., zero veriance). Input all amounts as positive values. Round your intermediate calculations and final answers to 2 decimal places.) 1. Predetermined overhead rate per MH Variable element per MH Fixed element per MH 2. Standard hours allowed for the actual production MHs 3. Variable overhead rate variance Variable overhead efficiency variance Fixed overhead budget variance Fixed overhead volume variance
