Exercise 10-4 Direct Labor and Variable Manufacturing Overhead Variances (LO10-2 Erle Company manufactures a small mp3 player called the Jogging Mate. The company uses standards to control its costs. The labor standards that have been set for one Jogging Mate mp3 player are as follows: Standard Hours 27 minutes Standard Rate per Hour Standard Cost $261 Book During August, 9.255 hours of direct labor time were needed to make 19,300 units of the Jogging Mate. The direct labor cost totaled $51,828 for the month. Required: 1 According to the standards, what direct labor cost should have been incurred to make 19,300 units of the Jogging Mate? By how much does this differ from the cost that was Incurred? (Round Standard labor time per unit to 2 decimal places.) Number of units manufactured Standard labor time per unit Total standard hours of labor time allowed Standard direct labor rate per hour Total standard direct labor cost Actual direct labor cost Standard direct labor cost Total variance unfavorable 2. Break down the difference in cost from (1) above into a labor rate variance and a labor efficiency variance. (Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (.e., zero variance). Do not round Intermediate calculations.) Labor rate variance Labor efficiency variance 3. The budgeted variable manufacturing overhead rate is $4.3 per direct labor-hour. During August, the company incurred $44,424 in variable manufacturing overhead cost. Compute the variable overhead rate and efficiency variances for the month. (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 and round your final answers to nearest whole dollar.) Variable overhead rate variance Variable overhead efficiency variance
