00 E9-17 (Algo) Calculating Variable Manufacturing Overhead Variances [LO 9-5] 1.91 points See Clear Company manufactures clear plastic CD cases. It applies variable overhead based on the number of machine hours used. Information regarding See Clear's overhead for the month of December follows: Standard Unit Cost eBook Variable manufacturing overhead Standard Quantity 0.2 machine hours per case Standard Rate $0.70 per machine hour Print $ 0.14 References During December, See Clear had the following actual results: Number of units produced and sold Actual variable overhead cost Actual machine hours 315,000 $ 45,000 60,000 Required: Compute See Clear'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 (i.e., zero variance).)
