Standard Quantity or Direct materials Direct labor Variable manufacturing overhead Total standard cost per unit Hours ? ? ? Standard Price or Rate $ 8.00 per yard Standard Cost ? $ ? ? $2 per direct labor-hour ? $ ? Overhead is applied to production on the basis of direct labor-hours. During March, 600 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 Labor rate variance Materials quantity variance Labor efficiency variance Variable overhead rate variance Variable overhead efficiency variance *For the month's production. Materials Used $ 15,360 Direct Labor $ 9,000 Variable Manufacturing Overhead $ 1,800 $ 13,965 ? $ 2,985 ? $ 600 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 Required: 900 $ 0.20 F 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. What is the standard cost of a single backpack? 2. What was the actual cost per backpack produced during March? 3. How many yards of material are required at standard per backpack? 4. What was the materials price variance for March if there were no beginning or ending inventories of materials? 5. What is the standard direct labor rate per hour?
