Answer: See explanation
Step-by-step explanation:
a. What is the Standard labor-hours allowed (SHI to ship 160,000 terms to customers?
Actual output = 160,000 items
Standard labour hour per time = 0.03 per time
Standard labor hour allowed = 160,000 × 0.03 = 4800 hours
b. What is the standard variable overhead cost allowed (SH SR) to ship 160,000 items to customers?
Standard variable overhead rate per hour = $3.25
Standard variable overhead cost allowed = 4800 × $3.25 = $15600
c. What is the variable overhead spending variance?
= $15600 - $20800
= $5200 Unfavorable
d. What is the variable overhead rate variance and the variable Overhead efficiency variance
Variable overhead rate variance:
= (Actual hours × Standard rate per hour ) - Actual variable overhead
= (6500 hours × 3.25) - $20800
= $21125 - $20800
= $325 F
Variable overhead efficiency variance:
= $3.25 (4800 - 6500)
= $3.25 (-1700)
= $5525 Unfavorable
