Kropf Inc. has provided the following data concerning one of the products in its standard cost system. Variable manufacturing overhead is applied to products on the basis of direct labor-hours. The company has reported the following actual results for the product for September: Required: a. Compute the materials price variance for September. b. Compute the materials quantity variance for September. c. Compute the labor rate variance for September. d. Compute the labor efficiency variance for September. e. Compute the variable overhead spending variance for September. f. Compute the, variable overhead efficiency variance for September. (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.) The direct materials and direct labour standards for one bottle of Clean-All spray cleaner are given below: During the most recent month, the following activity was recorded: a. 23,000 millilitres of material was purchased at a cost of $0.26 per millilitre. b. All of the material was used to produce 3,640 bottles of Clean-All. c. 600 hours of direct labour time was recorded at a total labour cost of $7,200. Assume that instead of producing 3,640 bottles of Clean-All during the month, the company produced only 2,000 bottles, using 19,000 millilitres of material. (The rest of the material purchased remained in raw materials inventory.) Requirect: Compute the direct materials price and quantity variances for the month. (Indicate the effect of each variance by selecting "F" for favourable, " U " for unfavourable, and "None" for no effect (i.e., zero variance).)
