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 Hours	Standard Rate per Hour	Standard Cost
18 minutes	$17.00	$5.10

During 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.

Alternatively, the variances can be computed using the formulas:

Labor rate variance = AH (AR SR)

Labor efficiency variance = SR (AH SH)
