b) diret laborers worked 55,000 hours at a rate of $15.00 per hour.

c) Total variable manufacturing overhead for the month was $280,500.

15) What is the variable overhead efficiency variance for March?

Variable overhead efficiency variance for March
SR (AH - SH)
Actual quantity of direct labor used (a)
Standard quantity allowed (b)
Variance (a) - (b) =(c )
Standard variable overhead rate/hour (d)
**Variable overhead efficiency variance (c ) x (d)
** If actual quantity of direct labor used exceed standard quantity of direct labor allowed,
variable overhead efficiency variance would be unfavorable and vice versa.
