Standard Product Cost, Direct Materials Variance H.J. Heinz Company uses standards to control its materials costs. Assume that a batch of ketchup (6,000 pounds) has the following standards: Standard Quantity Standard Price Whole tomatoes 7,500 lbs. $0.40 per lb. Vinegar 600 gal. 1.75 per gal. Corn syrup 50 gal. 8.00 per gal. Salt 500 lbs. 0.70 per lb. The actual materials in a batch may vary from the standard due to tomato characteristics. Assume that the actual quantities of materials for batch H3001 were as follows: 7,850 lbs. of tomatoes 575 gal. of vinegar 63 gal. of corn syrup 480 lbs. of salt a. Determine the standard unit materials cost per pound for a standard batch. Round your answer to the nearest cent. $ per lb. b. Determine the total direct materials quantity variance for batch H3001. Round your answer to the nearest cent. Enter a favorable variance as a negative amount, and an unfavorable variance as a positive amount. $
