Answer:
Standard labor-hours allowed= 7,400 direct labor Hours.
The standard variable overhead cost= $ 25,900
Variable overhead spending variance =$400
Variable overhead rate variance =$400
Variable overhead efficiency variance=$2,100
Explanation
a.) The standard labor-hours allowed (SH) to ship 185,000 items to customers
= 0.04 direct labor-hours x 185,000= 7,400 direct labor Hours.
b). The standard variable overhead cost allowed to ship 185,000 items to customers=
standard labor-hours SH × Standard Rate SR
7400 X $3.50= $ 25,900
c). Variable overhead spending variance is calculated as
Actual Overhead Costs - Actual hours x Standard Rate
= $27600 - 8,000 x 3.50 = $27600 -28,000
=$400
d1). Variable overhead rate variance =
Actual hours x Actual Variable Overhead Rate per Hour - Actual hours Standard Variable Overhead Rate per Hour
Variable overhead rate variance =8000 x (27600/8000) - 8000 x 3.50
8000 x 3.45 - 8000 x 3.50
27,600-28,000=$400
d2) Variable overhead efficiency variance= Actual Hours x Standard Rate - Standard Hours x Standard Rate
8000 x 3.50 -7400 x 3.50
28,000 -25,900
=$2,100
