Problem 10-15 Comprehensive Variance Analysis [LO1, LO2, LO3] Helix Company produces several products in its factory, including a karate robe. The company uses a standard cost system to assist in the control of costs. According to the standards that have been set for the robes, the factory should work 780 direct labor-hours each month and produce 2,600 robes. The standard costs associated with this level of production are as follows: Total Per Unitof Product Direct materials $53,248 $ 20.48 Direct labor $9,100 3.50 Variable manufacturing overhead $1,560 0.60 (based on direct labor-hours) During April, the factory worked only 755 direct labor-hours and produced 2,700 robes. The following actual costs were recorded during the month: Total of Product Per Unit Direct materials (9,450 yards) $ 56,700 $ 21.00 Direct labor $9,990 3.70 Variable manufacturing overhead 4,320 1.60 At standard, each robe should require 3.2 yards of material. All of the materials purchased during the month were used in production. Required: 1. Compute the materials price and quantity variances for April: (Input all amounts as positive values. Leave no cells blank - be certain to enter "0" wherever required. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Round your intermediate calculations to 2 decimal places and final answers to the nearest whole dollar. Omit the "$" sign in your response.) Materials price variance $ Materials quantity variance $ 2. Compute the labor rate and efficiency variances for April: (Input all amounts as positive values. Leave no cells blank - be certain to enter "0" 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). Do not round intermediate calculations. Round your final answers to the nearest dollar amount. Omit the "$" sign in your response.) Labor rate variance $ Labor efficiency variance $ 3. Compute the variable manufacturing overhead rate and efficiency variances for April: (Input all amounts as positive values. Leave no cells blank - be certain to enter "0" 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). Round your intermediate calculations to 2 decimal places and final answers to the nearest whole dollar. Omit the "$" sign in your response.)
