Answer:
the material quantity variance is $18,000 favorable
Step-by-step explanation:
The computation of the material quantity variance is as follows
Material quantity variance is
= standard cost × ( actual quanitity used - standard quantity usage per batch × number of batches produced)
= $3.00 × (78,000 - 60,000 × 1.4)
= $18,000 favorable
Hence, the material quantity variance is $18,000 favorable
