Cholla Companys standard fixed overhead rate is based on budgeted fixed manufacturing overhead of $22,200 and budgeted production of 30,000 units. Actual results for the month of October reveal that Cholla produced 28,000 units and spent $21,000 on fixed manufacturing overhead costs. Calculate Chollas fixed overhead rate and the fixed overhead volume variance. (Round "Fixed Overhead Rate" to 2 decimal places. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable.)
