Janet Dunn, who has just been appointed general manager of the Westwood Plant, has been given instructions to get things under control. Upon reviewing the plants income statement, Ms. Dunn has concluded that the major problem lies in the variable cost of goods sold. She has been provided with the following standard cost per swimming pool:

	Standard Quantity or Hours	Standard Price or Rate		Standard Cost
Direct materials	3.3 pounds	$ 2.80	per pound	$ 9.24
Direct labor	0.8 hours	$ 7.40	per hour	5.92
Variable manufacturing overhead	0.6 hours*	$ 2.90	per hour	1.74
Total standard cost per unit				$ 16.90

*Based on machine-hours.

During June the plant produced 5,000 pools and incurred the following costs:

1. Purchased 21,500 pounds of materials at a cost of $3.25 per pound.

2. Used 16,300 pounds of materials in production. (Finished goods and work in process inventories are insignificant and can be ignored.)

3. Worked 4,600 direct labor-hours at a cost of $7.10 per hour.

4. Incurred variable manufacturing overhead cost totaling $10,890 for the month. A total of 3,300 machine-hours was recorded.

It is the companys policy to close all variances to cost of goods sold on a monthly basis.

Required:

1. Compute the following variances for June:

a. Materials price and quantity variances.

b. Labor rate and efficiency variances.

c. Variable overhead rate and efficiency variances.

2. Summarize the variances that you computed in (1) above by showing the net overall favorable or unfavorable variance for the month.
