The variable overhead efficiency variance for the month is closest to:

A) $268 U
B) $268 F
C) $276 F
D) $276 U

The formula for variable overhead efficiency variance is:
Actual Hours - (Actual Production x Standard Hours per Unit)
In this case, we have:
Actual Hours = 6,400
Actual Production = 800 units
Standard Hours per Unit = 8 hours per unit
So, the calculation would be:
6,400 - (800 x 8) = 4,800 unfavorable
Since the result is unfavorable, we need to use the F (favorable) option that is closest to the result. The closest option is $268 F, so the answer is B.

SH = 9,300 units × 0.20 hours per unit = 1,860 hours
Variable overhead efficiency variance = (AH × SR)- (SH × SR)
= (AH - SH)× SR
= (1,820 hours - 1,860 hours)× $6.70 per hour
= (-40 hours)× $6.70 per hour
= $268 F
