Final answer:
For question 6, the fixed overhead spending variance (a) is $4,200 unfavorable. For question 7, the true statement about Skizone's overhead variances is that (B) the static fixed overhead amount is higher than the flexible fixed overhead amount.
Step-by-step explanation:
Question 6:
To find the fixed overhead spending variance (a), we need to subtract the other variance components from the total unfavorable spending variance of $2,300. According to the 4-Variance Analysis, the spending variance consists of spending variance, efficiency variance, and no variance.
The variable overhead spending variance is $6,500 favorable and the efficiency variance is $12,000 unfavorable, leaving us with an unfavorable spending variance of $2,300. Since there is no variance for fixed overhead, the fixed overhead spending variance (a) would be $2,300 - $6,500 = $4,200 unfavorable.
Question 7:
Looking at the information provided, we know that the only variance component for fixed overhead is no variance. Therefore, the statement that is true of Skizone's overhead variances is B) Static fixed overhead amount is higher than flexible fixed overhead amount.
