Question

Becton Labs, Inc., produces various chemical compounds for industrial use. One compound, called Fludex, is prepared using an elaborate distilling process. The company has developed standard costs for one unit of Fludex, as follows:

	Standard Quantity or Hours		Standard Price or Rate			Standard Cost
Direct materials	2.30	ounces	$	17.00	per ounce	$	39.10
Direct labor	0.60	hours	$	13.00	per hour		7.80
Variable manufacturing overhead	0.60	hours	$	2.50	per hour		1.50
Total standard cost per unit						$	48.40

During November, the following activity was recorded related to the production of Fludex:

1. Materials purchased, 11,500 ounces at a cost of $178,825.

2. There was no beginning inventory of materials; however, at the end of the month, 3,150 ounces of material remained in ending inventory.

3. The company employs 17 lab technicians to work on the production of Fludex. During November, they each worked an average of 160 hours at an average pay rate of $11.50 per hour.

4. Variable manufacturing overhead is assigned to Fludex on the basis of direct labor-hours. Variable manufacturing overhead costs during November totaled $3,000.

5. During November, the company produced 3,500 units of Fludex.

Required:

1. For direct materials:

a. Compute the price and quantity variances.

2. For direct labor:

a. Compute the rate and efficiency variances.

3. Compute the variable overhead rate and efficiency variances.

Answer 1

1)	for direct materials
	a.	price and quantity variance
			Standard	-	Actual	*	Actual	=	Variance
			price		price		quantiy
materials price variance			17		15.55		11,500	=	16675	F
			standard	-	Actual	*	Standard	=	Variance
			qty		qty		price
materials quantity variance			8050		8,350		17		5100	U
	b.	yes
2)	for direct labor
			Standard	-	Actual	*	Actual	=	Variance
			rate		rate		hours
labor price variance			13		11.5		2720	=	4080	F
			standard	-	Actual	*	Standard	=	Variance
			hours		hours		rate
labor efficiency variance			2100		2,720		13		8060	U
	b.	no
3)	for variable overhead
			Standard	-	Actual	*	Actual	=	Variance
			rate		rate		hours
Variable overhead rate			2.5		1.10		2,720	=	3800	F
			standard	-	Actual	*	Standard	=	Variance
			hours		hours		rate
variable overhead efficiency			2100		2,720		2.5		1550	U
