Variable overhead is applied on the basis of direct labor-hours. Compute the following variances for raw materials, direct labor, and variable overhead, assuming that the price variance for materials is recognized at point of purchase a. Direct materials quantity variance b. Direct materials price variance c. Direct labor efficiency variance e. Direct labor rate variance d. Variable overhead efficiency variance f.
