Exercise 10-4 Direct Labor and Variable Manufacturing Overhead Variances [LO 10-2, LO 10-3] Erie 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: During August, 9,550 hours of direct labor time were needed to make 20,000 units of the Jogging Mate. The direct labor cost totaled $60,165 for the month. Required: 1. According to the standards, what direct labor cost should have been incurred to make 20,000 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.) 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 (i.e., zero variance). Do not round intermediate calculations.) 3. The budgeted variable manufacturing overhead rate is $4.7 per direct labor-hour. During August, the company incurred $51,570 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.)
