Chapter 22 Evaluating Variances from Standard Costs case. There were 1,500 actual cases produced during August, which was than planned at the beginning of the month. Actual data for August were as follo ore s follows: Actual Direct Materials Actual Direct Materials Cream base Natural oils Bottle (8-oz.) Price per Unit $0.016 per oz. $0.32 per oz. $0.42 per bottle Quantity per Case 102 ozs. 31 ozs 12.5 bottles Actual Direct Labor Time per Case 19.50 min. 5.60 min. Actual Direct Labor Rate Mixing Filling $18.20 14.00 $305.00 Actual variable overhead Normal volume 1,600 cases The prices of the materials were different than standard due to fluctuations in market prices. The standard quantity of materials used per case was an ideal standard. The Mixing Depart ment used a higher grade labor classification during the month, thus causing the actual labor rate to exceed standard. The Filling Department used a lower grade labor classification during the month, thus causing the actual labor rate to be less than standard Instructions 10. Determine and interpret the direct materials price and quantity variances for the three materials 11. Det termine and interpret the direct labor rate and time variances for the two departments. Round hours to the nearest hour. 12. Determine and interpret the factory overhead controllable variance. 13. Determine and interpret the factory overhead volume variance. 14. Why are the standard direct labor and direct materials costs in (10) and (11) based on the actual 1,500-case production volume rather than the planned 1,250 cases of production used in the budgets for parts (6) and (7)? the calculations for parts
