Data table All - Star, Inc. uses a standard cost system and provides the following information. III (Click the icon to view the information.) All-Star allocates manufacturing overhead to production based on standard direct labor hours. All - Star reported the following actual results for 2024: actual number of units produced, 1,000; actual variable overhead, $3,800; actual fixed overhead, $3,500; actual direct labor hours, 1.500 Requirement 1. Compute the variable overhead cost and efficiency vatiances and fixed overhead cost and volume variances. Begin with the variable overhead cost and efficiency variances, Solect the required formulas, compute the varisble overhead cost and efficiency variances, and identify whether each variance is favorable (F) or unfavorable (U). (Abbreviations used: AC= aclual cost; AC= actual quantity; FOH= fixed overhead; SC= standard cost; SQ= standard quantity; VOH= variable overhead.)
