Miller Toy Company manufactures a plastic swimming pool at its Westwood Plant. The plant has

been experiencing problems as shown by its June contribution format income statement below:

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 plant’s 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 quanitity or hours, Standard Price or Rate, Standard Cost)

Direct materials . . . . . . . . . . . . . . . . . 3.0 pounds $2.00 per pound $ 6.00

Direct labor . . . . . . . . . . . . . . . . . . . . 0.8 hours $6.00 per hour 4.80

Variable manufacturing overhead . . . 0.4 hours* $ 3.00 per hour 1.20

Total standard cost . . . . . . . . . . . . . . $12.00

*Based on machine hours.

During June the plant produced 15,000 pools and incurred the following costs:

a. Purchased 60,000 pounds of materials at a cost of $1.95 per pound.

b. Used 49,200 pounds of materials in production. (Finished goods and work in process inventories

are insignifi cant and can be ignored.)

c. Worked 11,800 direct labor hours at a cost of $7.00 per hour.

d. Incurred variable manufacturing overhead cost totaling $18,290 for the month. A total of

5,900 machine hours was recorded.

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

Required:

1. Compute the following variances for June:

a. Direct materials price and quantity variances.

b. Direct labor rate and effi ciency variances.

c. Variable overhead rate and effi ciency variances.

2. Summarize the variances that you computed in (1) above by showing the net overall favorable

or unfavorable variance for the month. What impact did this fi gure have on the company’s income

statement? Show computations.

3. Pick out the two most signifi cant variances that you computed in (1) above. Explain to

Ms. Dunn possible causes of these variances.
