Problem 10-15 (Algo) Comprehenslve Varlance Analysls [LO10-1, LO10-2, LO10-3] Miller Toy Company manufactures a plastic swimming pool at its Westwood Plant. The plant is experiencing problems as shown by its June contribution format income statement below: Contains direct materials, direct labor, and variable manufacturing overhead. Janet Dunn, who has just been appointed general manager of the Westwood Plant, has been given instructions to "get things under control." Upon reviewing the plant's income statement, Ms. Dunn concluded the major problem lies in the variable cost of goods sold. She has been provided with the following standard cost per swimming pool: *Based on machine-hours. During June, the plant produced 8,000 pools and incurred the following costs: a. Purchased 33,000 pounds of materials at a cost of $295 per pound. b. Used 27,800 pounds of materials in production. (Finished goods and work in process inventories are insignificant and can be ignored.) c. Worked 3,800 direct labor-hours at a cost of $6.20 per hour. d. Incurred variable manufacturing overhead cost totaling $4,560 for the month. A total of 1,900 machine-hours was recorded. It is the company's policy to close all variances to cost of goods sold on a monthly basis. Requlred: 1. Compute the following variances for June: a. Materials price and quantity variances. b. Labor rate and efficiency variances. c. Variable overhead rate and efficiency variances. 2. Summarize the variances you computed in requirement 1 by showing the net overall favorable or unfavorable variance for the month. 1a. Compute the following variances for June, materials price and quantity variances. 1b. Compute the following variances for June, labor rate and efficiency variances. 1c. Compute the following variances for June, variable overhead rate and efficiency variances. Note: Do not round your 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). Input all amounts as positive values.
