Answer:
$78,750 unfavorable
Explanation:
Total labor variance can be divided into direct labor efficiency variance and the direct labor rate variance
Direct labor efficiency variance (DLEV):
DLEV = (Expected labor hours - actual labor hours)*standard rate
[tex]DLEV=(0.01*510,000 - 13,000)*7,50\\DLEV = -59,250[/tex]
Direct labor rate variance (DLRV):
DLRV = Actual labor hours * (Standard Rate - Actual Rate)
[tex]DLRV = 13,000*(7.50 - 9.00)\\DLRV = -19,500[/tex]
Since both values are negative, they are both unfavorable and the total labor variance (TLV) is given by:
[tex]DLRV = 13,000*(7.50 - 9.00)\\DLRV = 59,250 + 19,500\\TLV = \$ 78,750 \ unfavorable[/tex]
