Answer:
$426 Favorable
$1,278 Unfavourable
Step-by-step explanation:
Direct material cost variance = Standard cost - Actual cost
= 65
7,100*0.9*0.60 - 7,100*1.2*0.40
=3,834-3,408
= $426 Favorable
Direct labor efficiency variance = (standard quantity - actual quantity)*standard price
= (7,100*0.9- 7,100*1.2)*0.60
=6,390-8,520*0.60
=-2,130*0.60
=$-1,278 Unfavourable
