To achieve this level of production, Slick purchased and used 16,500 gallons of direct materials at a cost of $20,359. It also incurred average direct labor costs of $14 per hour for the 4,031 hours worked in May by its production personnel. Manufacturing overhead for the month totaled $9,019, of which $2,200 was considered fixed. Slick's standard cost information for each case of synthetic motor oil is as follows.

Standard quantity allowed per case		3.25	gallons
Direct labor standard rate	$	16	per hour
Standard hours allowed per case		0.75	direct labor hours
