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 Quantity or HoursStandard Priceor RateStandard Cost

Direct materials3.9 pounds$2.50 per pound$9.75

Direct labor 0.8 hours$8.00 per hour 6.40

Var. man. O.H.0.2 hours*$3.50 per hour 0.70

Total standard cost per unit $16.85

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

Purchased 24,500 pounds of materials at a cost of $2.95 per pound.

Used 19,300 pounds of materials in production. (Finished goods and work in process inventories are insignificant and can be ignored.)

Worked 4,600 direct labor-hours at a cost of $7.70 per hour.

Incurred variable manufacturing overhead cost totaling $5,070 for the month. A total of 1,300 machine-hours was recorded.

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

1a. Compute the following variances for June, materials price and quantity variances.

1b. Compute the following variances for June, labor rate and efficiency variances.

1c. Compute the following variances for June, variable overhead rate and efficiency variances.
