Exercise 25-6 lewis company’s standard labor cost of producing one unit of product dd is 3.1 hours at the rate of $12.7 per hour. during august, 42,200 hours of labor are incurred at a cost of $12.80 per hour to produce 13,500 units of product dd. (a) compute the total labor variance. total labor variance $ (b) compute the labor price and quantity variances. labor price variance $ labor quantity variance $ (c) compute the labor price and quantity variances, assuming the standard is 3.4 hours of direct labor at $12.95 per hour. labor price variance $ labor quantity variance $

a. $8,665 favorable

b. The labor price and quantity variance is  $4,220 favorable and $4,445 favorable respectively

c. The labor price and quantity variance is  $10,550 unfavorable and $ 47,915 unfavorable respectively

Explanation:

a. The computation of the total labor variance is shown below:

= (Actual hours × Actual rate) - (Standard hours × standard rate)

= (42,200 hours × $12.80 per hour) - (13,500 units × 3.1 hours × $12.7 per hour)

= $540,160 - $531,495

= $8,665 favorable

b.The computation of the labor price variance is shown below:

= Actual Hours × (Actual rate - standard rate)

= 42,200 × ($12.80 per hour - $12.7 per hour)

= 42,200 × $0.1 per hour

= $4,220 favorable

The computation of the labor quantity variance is shown below:

= Standard Rate × (Actual hours - Standard hours)

= $12.70 per hour × (42,200 hours - 41,850 hours)

= $12.70 per hour × 350 hours

= $4,445 favorable

c. The computation of the labor price variance is shown below:

= Actual Hours × (Actual rate - standard rate)

= 42,200 × ($12.7 per hour - $12.95 per hour)

= 42,200 ×  - $0.25 per hour

= $10,550 unfavorable

The computation of the labor quantity variance is shown below:

= Standard Rate × (Actual hours - Standard hours)

= $12.95 per hour × (42,200 hours - 45,900 hours)

= $12.95 per hour × - 3,700 hours

= $ 47,915 unfavorable
