Preble Company manufactures one product. Its variable manufacturing overhead is applied to production based on direct labor-hours and its standard cost card per unit is as follows:

Direct materials: 4 pounds at $10 per pound	$	40
Direct labor: 2 hours at $16 per hour		32
Variable overhead: 2 hours at $6 per hour		12
Total standard cost per unit	$	84

The planning budget for March was based on producing and selling 30,000 units. However, during March the company actually produced and sold 34,500 units and incurred the following costs:

a.	Purchased 150,000 pounds of raw materials at a cost of $9.20 per pound. All of this material was used in production.
b.	Direct laborers worked 62,000 hours at a rate of $17 per hour.
c.	Total variable manufacturing overhead for the month was $390,600.
