Highland Company produces a lightweight backpack that is popular with college students. Standard variable costs relating to a single backpack are given below: Standard Quantity or Hours Standard Price or Rate Standard Cost Direct materials Direct labor ? $5.00 per yard $ ? ? ? ? per direct Variable manufacturing overhead ? $ 2 labor-hour ? Total standard cost per unit $ ? Overhead is applied to production on the basis of direct labor-hours. During March, 440 backpacks were manufactured and sold. Selected information relating to the month's production is given below: Total standard cost allowed* Actual costs incurred Materials price variance Materials quantity variance Labor rate variance Labor efficiency variance Variable overhead rate variance Variable overhead efficiency variance *For the month's production. Materials Used $ 9,460 $ 8,272 Direct Labor $6,468 ? Variable Manufacturing Overhead $1,232 $1,738 ? $ 880 U ? ? ? ? The following additional information is available for March's production: Actual direct labor-hours Difference between standard and actual cost per backpack produced during March 660 $ 0.20 F Required: Hint: It may be helpful to complete a general model diagram for direct materials, direct labor, and variable manufacturing overhead before attempting to answer any of the requirements. 1.
