Answer:
1. Standard quantity of labor-hours allowed 4,800
2. Standard variable overhead cost allowed $15,600
3. Variable overhead spending variance 5,200 U
4. Variable overhead rate variance 325 F
5.Variable overhead efficiency variance 5,525 U
Step-by-step explanation:
1. Calculation for Standard quantity of labor-hours allowed
Standard quantity of labor-hours allowed = 160,000*0.03
Standard quantity of labor-hours allowed= 4,800
Therefore Standard quantity of labor-hours allowed is 4,800
2. Calculatuon for Standard variable overhead cost allowed
Standard variable overhead cost allowed= 4,800*$3.25
Standard variable overhead cost allowed = $15,600
Therefore the Standard variable overhead cost allowed is $15,600
3. Calculation for Variable overhead spending variance
Variable overhead spending variance = $15,600 - $20,800
Variable overhead spending variance = 5,200 U
Therefore the Variable overhead spending variance is 5,200 U
4. Calculation for Variable overhead rate variance
Variable overhead rate variance= ($3.25 - $20,800/6,500)*6,500
Variable overhead rate variance=($3.25-$3.2)*6,500
Variable overhead rate variance= 325 F
Therefore The Variable overhead rate variance= 325 F
5. Calculation for Variable overhead efficiency variance
Variable overhead efficiency variance= (4,800-6,500)*3.25
Variable overhead efficiency variance = 1,700*3.25
Variable overhead efficiency variance= 5,525
Therefore the Variable overhead efficiency variance is 5,525 U
