Answer and Explanation:
The computation is shown below:
a. Direct material price variance
= 80,000 × ($2.65 - $2.5)
= $12,000 unfavorable
Direct material quantity variance
= $2.5 × (80,000 - 86,000)
= -$15,000 favorable
ANd, the total direct material cost variance
= $12,000 unfavorable - $15,000 favorable
= -$3,000 favorable
2. The direct material price variance should be reported to the purchasing department while the direct material quantity variance should be reported to the production supervisor and the total material cost variance should be reported to the senior plant management
