I only need help with number 5 (Variable Overhead Rate Variance).

Ch 4 Erie Company manufactures a mobile fitness device called the Jogging Mate. The company uses standards to control its costs. The labor standards that have been set for one Jogging Mate are as follows: Standard Standard Rate Standard per Hour $17.00 Hours 18 minutes Cost $5.10 12 points 030108During August, 5,750 hours of direct labor time were needed to make 20,000 units of the Jogging Mate. The direct labor cost totaled $102,350 for the month. Required: 1. What is the standard labor-hours allowed (SH) to makes 20,000 Jogging Mates? 2. What is the standard labor cost allowed (SH x SR) to make 20,000 Jogging Mates? 3. What is the labor spending variance? 4. What is the labor rate variance and the labor efficiency variance? eBook Hint Print References5. The budgeted variable manufacturing overhead rate is $4 per direct labor-hour. During August, the company incurred $21,850 in variable manufacturing overhead cost. Compute the variable overhead rate and efficiency variances for the month. (For requirements 3 through 5, 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. Do not round intermediate calculations.) 1. Standard labor-hours allowed 2. Standard labor cost allowed 3. Labor spending variance 4.
