Kowaleski Corporation makes a product with the following standard costs: Standard Price or Rate Standard Quantity Direct materials Direct labor Variable overhead or Hours 4.0 grams $ 7.00 per granm 0.5 hours $ 14.00 per hour 0.5 hours 4.00 per hour In June the company produced 4,500 units using 19,250 grams of the direct material and 2,490 direct labor- hours. During the month the company purchased 24,400 grams of the direct material at a price of $6.80 per gram. The actual direct labor rate was $14.60 per hour and the actual variable overhead rate was $3.90 per nour. The materials price variance is computed when materials are purchased. Variable overnead is applied on the basis of direct labor-hours Required: Compute the following variances for raw materials, direct labor, and variable overhead, assuming that the price variance for materials is recognized at point of purchase: (Input all amounts as positive values. Do not round intermediate calculations. Leave no cells blank - be certain to enter "O" wherever required. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance.)
