Answer:
Cost variance= 7 unfavorable
Explanation:
Giving the following information:
Each bat requires 1 kg of aluminum at $18 per kg and 0.25 direct labor hours at $20 per hour. Overhead is assigned at the rate of $40 per direct labor hour. Assume the actual cost to manufacture one metal bat was $40.
Estimated cost= 18 + 0.25*20 + 0.25*40= 33
Actual cost= 40
Cost variance= 7 unfavorable
