Answer:
D) $18,000 Favorable
Explanation:
The computation of the material quantity variance is given below:
Material quantity variance is
= standard cost × ( actual quantity used - standard quantity usage per batch × batches produced)
= $3.00 × (78,000 - 60,000 × 1.4)
= $18,000, favorable
hence, the material quantity variance is $18,000 favorable
