Check my work E9-13 (Algo) 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 LLU's standard cost card follows: Standard Standard Standard Quantity Unit Cost Variable manufacturing 0.6 $0.80 $0.48 overhead Rate During August, LLL had the following actual results: Unico produced and sold 24,000 Actual variable overhead $9,390 Atual direct labor hours 15,000 Required: Compute Liu'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. "U" for unfavorable, and "None" for no effect (ie, zero variance).)
