Please help me with this question. I've started it but am stumped on the others.

Highland Company produces a lightweight backpack that is popular with college students. Standard variable costs relating to a single backpack are given below: Direct materials Direct labor Variable manufacturing overhead Total standard cost Standard Quantity or Standard Price Hours or Rate ? $7.5 per yard ? ? ? $3.6 per direct labor-hour Standard Cost $? ? ? $? Overhead is applied to production on the basis of direct labor-hours. During March, 1,000 backpacks were manufactured and sold. Selected information relating to the month's production is given below: Total standard cost allowed* Actual costs incurred Direct materials price variance Direct materials quantity variance Direct labor rate variance Direct labor efficiency variance Variable overhead rate variance Variable overhead efficiency variance Materials Used $22,500 $21,942 ? $1,350 U Direct Labor $16,600 ? Variable Manufacturing Overhead $7,200 $6,600 ? ? ? *For the month's production. The following additional information is available for March's production: Actual direct labor-hours Standard overhead rate per direct labor-hour Standard price of one yard of materials Difference between standard and actual cost per backpack produced during March 2,200 $3.6 $7.5 $.95 F Requirement 1: What is the standard cost of a single backpack?
