Answer and Explanation:
The computation is shown below:
(a)
Direct material price variance is
= ($2.5 - $2.55) × 39,600
= $1,980 Unfavourable
(b)
Direct material quantity variance is
= (3,400 × 12 - 39,600) × 2.50
= $3,000 favorable
(c)
And, Direct material cost variance is
= (3,400 × 12 × $2.50) -( 39,600 × $2.55)
= $1,020 unfavorable
The same is to be considered
