Standard Costs and Operating Performance Measures 483
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 insignificant 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 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. What impact did this figure have on the company's income statement? Show computations.
3. Pick out the two most significant variances that you computed in (1) above. Explain to Ms. Dunn possible causes of these variances.
