Exercise 23-15 (25 minutes)
Part 1
Direct materials price variance:
Actual cost of direct materials used (16,000 x $4.05)..............................$ 64,800
Direct materials quantity variance:
Actual quantity used x Standard price (16,000 x $4.00)..........................$ 64,000
Part 2
Direct labor rate variance:
Actual hours x Actual rate per hour (5,545 x $19.00***)...........................$105,355
Direct labor efficiency variance:
Actual hours x Standard rate per hour (5,545 x $20.00)..........................$110,900

2.
The unfavorable labor rate variance in October means the actual rate for an
hour of labor is greater than budgeted. The favorable labor efficiency
variance means the actual hours used are less than budgeted. Together,
Exercise 23-17 (20 minutes)
1. Predetermined overhead rate computations
Expected volume.................................................................... 75%
Expected total overhead........................................................ $2,100,000
2. Variable overhead cost variance
Variable overhead cost incurred [given]..................................................$1,375,000
Fixed overhead cost variance
Fixed overhead cost incurred [given].............................................$ 628,600
Exercise 23-18A (20 minutes)
1.
Variable overhead spending and efficiency variances
Actual Overhead
AH x AVR AH x SVR
Applied Overhead
SH x SVR
Interpretation:
The $15,000 unfavorable spending variance means the actual cost of
variable overhead is more than budgeted. This unfavorable variance can
The $40,000 favorable efficiency variance occurs because the actual labor

Fixed overhead spending and volume variances
Actual Overhead Budgeted Overhead Applied Overhead
Interpretation
The $40,000 unfavorable volume variance is the result of the company

Variable overhead spending variance................................... $15,000 U
The controllable variance refers to activities that are considered within

2. Overhead controllable variance*
Total actual overhead (given) $305,000
Flexible budget overhead
* Alternative solution approach: We know the overhead controllable variance is equal to the
total overhead variance less the overhead volume variance. Then, using the results from parts
1 and 2, we can compute the overhead controllable variance as
