Can someone help me with Labor Rate Variance, Variable Overhead Rate Variance and Variable overhead efficiency variance?

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:

Standard Hours	Standard Rate per Hour	Standard Cost
24 minutes	$5.60	$2.24

During August, 8,490 hours of direct labor time were needed to make 19,500 units of the Jogging Mate. The direct labor cost totaled $45,846 for the month.

The direct labor cost totaled $45.846 for the month. Required: 1. According to the standards, what direct labor cost should have been incurred to make 19,500 units of the Jogging Mate? By how much does this differ from the cost that was incurred?

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).
