Answer:
1)
direct materials price variance = actual quantity x (actual price - standard price)
direct materials price variance = 7,820 x ($5.30 - $15) = 7,820 x (-$9.70) = -$75,854 favorable
direct materials usage variance = standard price x (actual usage - standard usage)
direct materials usage variance = $15 x (7,820 - 9,660) = -$27,600 favorable
2)
direct labor price variance = actual hours x (actual rate - standard rate)
direct labor price variance = 2,460 x ($12.30 - $15) = 2,460 x (-$2.70) = -$6,642 favorable
direct labor usage (efficiency) variance = standard rate x (actual hours - standard hours)
direct labor usage (efficiency) variance = $15 x (2,460 - 3,680) = $15 x (-1,220) = -$18,300 favorable
