The following data relate to the direct materials cost for the production of 10,000 automobile tires: actual: 145,000 lbs. at $2.80 per lb. standard: 150,000 lbs. at $2.75 per lb. a. determine the direct materials price variance, direct materials quantity variance, and total direct materials cost variance. enter a favorable variance as a negative number using a minus sign and an unfavorable variance as a positive number. direct materials price variance $ unfavorable direct materials quantity variance $ favorable total direct materials cost variance $ favorable b. the direct materials price variance should normally be reported to the purchasing department . if lower amounts of direct materials had been used because of production efficiencies, the variance would be reported to the production supervisor . if the favorable use of raw materials had been caused by the purchase of higher-quality raw materials, the variance should be reported to the
