Answer:
The correct answer is B.
Step-by-step explanation:
Giving the following information:
Actual number of cars detailed 110
Actual direct labor hours used 275
Standard direct labor cost per hour $8.46
Standard direct labor per car 1.5
To calculate the direct labor efficiency variance, we need to use the following formula:
Direct labor time (efficiency) variance= (Standard Quantity - Actual Quantity)*standard rate
Actual quantity= 1.5*110= 165 hours
Direct labor time (efficiency) variance= (165 - 275)*8.46
Direct labor time (efficiency) variance= $930.6 unfavorable
