E9-11 Calculating Variable Manufacturing Overhead Variances [LO 9-5] Lamp Light Limited (LLL) manufactures lampshades. It applies variable overhead on the basis of direct labor hours. Information from LLL's standard cost card follows: Standard Standard Standard QuantityRate Unit Cost Variable manufacturing 0.6 S0.80 0.48 overhead During August, LLL had the following actual results: Units produced and sold Actual variable overhead Actual direct labor hours 24,100 $ 9,400 15,100 Required: Compute LLL's variable overhead rate variance, variable overhead efficiency variance, and over- or underapplied variable overhead. (Do not round intermediate calculations. Indicate the effect of each variance by selecting "F" for Favorable/Overapplied and "U" for Unfavorable/Underapplied.)
