Answer:
Variable manufacturing overhead rate variance = 80,000 favorable
Explanation:
Given:
Overhead rate variance = $1.70 per hour
Total machine hour = 160,000 hour
Actual overhead costs = $192,000
Find:
Variable manufacturing overhead rate variance
Computation:
Variable manufacturing overhead rate variance = [Standard overhead rate - Actual overhead rate]Actual hour
Variable manufacturing overhead rate variance =[1.7 - (192,000 / 160,000)]160,000
Variable manufacturing overhead rate variance = [1.7 - (1.2)]160,000
Variable manufacturing overhead rate variance = [0.5]160,000
Variable manufacturing overhead rate variance = 80,000 favorable
