calculate parker plastics variable overhead rate and efficiency variances and its over or underapplied variable overhead

Direct materials (plastic) Direct labor Variable manufacturing overhead (based on direct labor hours) Fixed manufacturing overhead ($289,280 - 904,000 unita) Standard Standard Price Quantity (Rate) 9 sq ft. $ 0.92 per sq. ft. 0.25 hr. $10.40 per hr. 0.25 hr. $ 1.60 per hr. Standard Unit Cost $8.28 2.60 0.40 0.32 Parker Plastic had the following actual results for the past year. Number of units produced and sold Number of square feet of plastic used Cost of plastic purchased and used Number of labor hours worked Direct labor cost Variable overhead cost Pixed overhead cost 1,200,000 11,100,000 $ 9,990,000 302,000 $ 3, 110,600 $ 496,000 359,000 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 (l.e., zero variance).)
