  1. Compute direct materials price and quantity variance.
  2. Compute direct labor rate and efficiency variance.


(1) Materials variances

i. Direct materials price variance:


ii. Direct materials quantity variance:


*2,500 bags × 7.2 lbs = 18,000 lbs

(2) Labor Variances

i. Direct labor rate variance:


ii. Direct labor efficiency variance:


*2,500 bags × 0.4 hours = 1,000 hours
