PROBLEM 11-10. Comprehensive Variance Problem [10 2, 3, 4, 6] Antikron Company produces rubber seals used in the aerospace industry. Standards call for 3 pounds of material at $2,so per pound for each seal. The standard cost for labor is 1.5 hours at $15 per hour. Standard over-head is $10 per unit. For the year 2015, expected production is 130,000 seals with fixed overhead of $130,000 and variable overhead of $9 per seal. During 2015, a total of 125,000 seals were produced. The company purchased 455,000 pounds of material for $1,150,000. Production required 425,000 pounds of material. The cost of direct labor incurred was $2,900,000 with an actual aver-age wage rate of $15.25 per hour. Actual overhead for the year was $900,000. Required a. Determine the standard cost per seal. b.
