E9-10 (Algo) Calculating Variable Overhead Variances (LO 9-5) Parker Plastic, Inc., manufactures plastic mats to use with rolling office chairs. Its standard cost information for last year follows: Direct materiale plastic) Direct labor Variable manufacturing overhead (based on direct labor hours) Tixed manufacturing overhead (5500,040 + 926,000 units) Standard Standard Price Quantity (Rate) 13 sq ft. $ 0.70 per sq. ft. 0.25 hr. $12.20 per hr. 0.25 hr. $. 1.40 per hr. Standard Unit Cost $9.10 3.05 0.35 0.50 Parker Plastic had the following actual results for the past year Number of units produced and sold Number of square feet of plastio used cost of plastie purchased and used Number of labor hours worked Direct labor cost Variable overhead cost Pixed overhead cost 1,200,000 12,200,000 $ 7,320,000 324,000 $ 3,855,600 $ 1,300,000 $ 381,000 Required: Calculate Parker Plastic's variable overhead rate and efficiency variances and its 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 (le, zero variance).)
